, which was supported by President Obama.
Since the Pennsylvania primaries are closed, the poll noted that Specter could not be assisted by support from moderates or Democrats.
Clay F. Richards, assistant director of the Quinnipiac University Polling Institute, said of the poll results, "Pennsylvania Republicans are so unhappy with Sen. Specter’s vote for President Barack Obama's Stimulus Package and so-called pork barrel spending that they are voting for a former Congressman they hardly know."
A March 2009 article in ''
The Hill'' quoted Specter as stating he was considering leaving the Republican party to run for re-election as an Independent candidate. Specter later denied the validity of those claims,
announcing on March 18, "To eliminate any doubt, I am a Republican, and I am running for reelection in 2010 as a Republican on the Republican ticket." However, on April 28, 2009, Specter announced he was leaving the Republican Party and becoming a Democrat because he disagreed with the increasingly conservative direction the Republican Party was heading in and found his personal philosophy was now better aligned with the Democrats. Although Specter said that he primarily based his decision on principle, he also admitted it was partially due to his poor chances at winning the Republican primary: "I have traveled the state and surveyed the sentiments of the Republican Party in Pennsylvania and public opinion polls, observed other public opinion polls and have found that the prospects for winning a Republican primary are bleak."
Prior to switching parties, Specter said he had been assured by Senate Majority Leader
Harry Reid
Harry Mason Reid Jr. (; December 2, 1939 – December 28, 2021) was an American lawyer and politician who served as a United States Senate, United States senator from Nevada from 1987 to 2017. He led the Senate Democratic Caucus from 2005 to 2 ...
that he would keep his seniority on the Senate if he joined the Democratic Party.
The arrangement displeased some Senate Democrats, and, on May 3, the Senate voted to strip him of his seniority in spite of this. This temporarily made Specter the most junior Democrat in the Senate and severely limited his influence as a legislator.
Nevertheless, Specter's decision was praised by many major Democrats, including Reid and President Barack Obama, who promised to campaign for him. Republicans, however, criticized the decision, accusing Specter of betraying his principles and party to preserve his political career.

While most Democrats embraced the long-time Senator, Sestak issued a statement criticizing Specter's decision, declaring it an opportunist move that should have been made in consultation with Pennsylvanians rather than the Senate Democratic leadership and the Washington political establishment.

, had planned on running for the Democratic nomination and initially announced Specter's party change would not affect his decision to run. However, Torsella announced on May 14 he was dropping out of the race because Specter's decision changed the political landscape, and he wanted to avoid a campaign that "would probably be negative, personal, and more about Senator Specter's past than our common future". It had been reported that Governor Rendell, for whom Torsella previously worked as an aide, pushed for Torsella to step aside so Specter could run unopposed, but Torsella's staff denied those claims.
Despite Torsella's departure, Sestak continued to consider entering the race and began gaining support from the Democratic party's more liberal factions like the

Sestak did not dispute the authenticity of the letter, but told the press he wanted to discuss the matter with his family before making a formal decision. Sestak told media outlets he realized President Obama wished him not to run against Specter, but that he felt the choice should be with the voters of Pennsylvania rather than the president. Governor Rendell overtly tried to convince him not to run, believing it would damage Sestak's own political future, plus cost the Democratic Party both Sestak's House seat and possibly damage Specter's general election chances.

Pennsylvania Rep. William C. Kortz and retired manufacturer Joseph Vodvarka also ran in the Democratic primary, but neither remained for the duration of the race. Kortz, who was little known outside the western Pennsylvania area, dropped out of the race on January 14, 2010, after raising only $20,000 of the $2 million he sought to raise for his campaign. Vodvarka, an
Allegheny County man who had been mostly overlooked throughout the race, was formally removed from the ballot in mid-April 2010 after it was revealed he failed to garner the minimum number of signatures for a nominating petition.
Campaign
Early months
Both candidates started the campaign well-funded. Sestak had more than $3 million available from his House fund to use toward starting a Senate campaign,
and raised an additional $1 million by June 30, 2009, which brought his total to about $4.2 million. Sestak called it the largest campaign war-chest of any Senate challenger. Specter, however, was ahead with $6.7 million in campaign funding as of March 31.
Sestak also faced challenges arising from his low name recognition and Specter's support among high-profile members of the Democratic establishment, like Obama and Biden.
Specter spent the early months of his campaign trying to reestablish and strengthen his Democratic credentials, seeking union support and making speeches highlighting his support of positions supported by the party, such as the economic stimulus package, reforming health care, increasing the minimum wage, protecting abortion rights and supporting

, Specter said, "I'm again a Democrat and I'm pleased and proud to be a Democrat."
Commentators observed that Sestak's involvement in the race would test Specter's loyalty to the Democratic party and likely force him to make more liberal votes in the Senate.
Even before Sestak formally declared his candidacy on August 4, 2009, Specter and Sestak began exchanging criticisms about each other that were so heated, ''The New York Times'' writer Janie Lorber suggested: "the contest will become one of the more vicious for next year's midterm elections."
Sestak repeatedly said Specter was not a "real Democrat" and continued to assert Specter's switch was based on self-preservation rather than principles.
Specter called Sestak a "flagrant hypocrite" for questioning Specter's loyalty to the Democratic Party, citing the fact that Sestak himself was registered as an Independent until he became a Democrat in 2006, just before he ran for Congress. Sestak claimed that was because he was serving in the military and wished to be nonpartisan. However, Specter called that a "lame excuse for avoiding party affiliation ... undercut by his documented disinterest in the political process", pointing out that records indicated Sestak voted in only 12 out of 35 elections from 1971 to 2005.
A day after Sestak formally entered the race, Specter described Sestak's recent 67-county tour as a "taxpayer-financed self-promotion tour around the state".
Specter's campaign also accused Sestak of neglecting his duties in the House and missing more than 100 votes in the last year, which Specter called the worst attendance record for any Pennsylvania Congressman.
Sestak responded to the latter point that most of the missed votes were procedural in nature,
and were missed because of the statewide tour and because he visited his father, who was dying at the time.
Sestak accused Specter of launching a "GOP negative style campaign", which Specter denied.
Toomey and Obama get involved

Specter dismissed suggestions that his recent Democratic votes were politically motivated by the primary, and cited his support of the
Lilly Ledbetter Fair Pay Act and
Children's Health Insurance Reauthorization Act as proof of his Democratic credentials. Sestak argued that a change in leadership was necessary and that his military background as a United States Navy admiral gave him the necessary experience. Sestak also pointed out that Specter worked with former Senator

However, a straw poll of 250 online activists attending the event showed Sestak was preferred to Specter by a vote of 46 percent to 10 percent.

described it as an "informal pact" between Sestak and Toomey to weaken their joint rival, something the two men denied.
Commentators suggested Toomey was willing to help Sestak at this stage of the race because he preferred Sestak as a general election opponent over Specter, who could possibly draw Republican and Independent voters from Toomey.
Also in September, Obama appeared in a 30-second television ad for Specter, praising him for his support of the President's economic recovery initiatives. A September poll by Franklin & Marshall College found Specter maintained a 37 percent to 11 percent lead over Sestak, but also that 54 percent of people felt a change was needed as opposed to 34 percent who felt Specter deserved a sixth term. That poll also found 73 percent felt they did not know enough about Sestak to form an opinion, which pollster Madonna said indicated the race would be focused more on Specter's incumbency and record than about Sestak or Toomey.

Michael Smerconish also spoke on Specter's behalf.
Senate Majority Leader Reid took the unusual steps of scheduling no Senate votes that day so both Specter and Pennsylvania Senator
Bob Casey, Jr. could attend the fundraiser.
That move drew criticism from Republicans,
as well as from Sestak, who felt Specter was skirting his Senate responsibilities, yet hypocritically criticizing Sestak at the same time for missing more than 100 votes in the U.S. House. The event was expected to raise about $2.5 million, which was to be split between Specter's campaign and the Democratic Senatorial Campaign Committee.
After the fundraiser, Obama and Specter traveled via

convention. There, Specter assured the audience he would support the
Employee Free Choice Act, a proposed bill that would make union formation easier, which Specter had previously opposed as a Republican.
Specter maintains lead
As the primary entered into October, Specter continued to criticize Sestak on his record of missed votes in Congress. He claimed Sestak missed 122 in the past year, or nearly 17 percent of his total votes, whereas Specter missed four. In a letter, Specter told Sestak he should drop out of the campaign and start voting on a more consistent basis, or resign from the House "so he can cease to be a burden to the taxpayers".
Around the same time, Sestak launched a website called "The Real Specter", which highlighted the right-leaning votes Specter made and alliances he held during his 29 years as a Republican in the senate. Specter continued to maintain a significant lead against Sestak of 19 percentage points, according to a Quinnipiac University poll released that month.
But Sestak pointed out that the gap was 32 points in July, and cited the poll as proof that he was gaining ground in the race.
Also that month, new reports indicated Toomey was growing in popularity and, in one poll, was actually ahead of Specter, with 43 percent of respondents saying they would vote for him compared to 42 percent for Specter. This was attributed by some to the challenge presented by Sestak and the declining popularity of Obama, whose approval rating had dropped from 56 percent in July to 49 percent in October.
On October 14, Specter reported he had raised $1.8 million during the previous three-month period, bringing his total to about $8.7 million. The Senator said that he was aided in large part by his September 15 fundraiser hosted by Obama. In that same period, Sestak raised only $758,000, about a quarter million dollars lower than the previous quarter, making his total allocation about $4.7 million.
Sestak continued working hard to overcome his name recognition problem, seldom turning down interview requests and asking his staff to work six 12-hour days a week. As a result, Sestak saw a large amount of turnover in his staff, going through nearly half a dozen press secretaries and several chiefs of staff.
Sestak called on Specter to participate in six debates, one for each media market in Pennsylvania, but Specter only agreed to participate in one because that was the amount of debates he participated in as a Republican.
On December 7, Sestak was endorsed by Congressman
Barney Frank

. The endorsement was important to Sestak because it was the first time a prominent member of Congress broke with the Democratic establishment to back him over Specter.
Frank also said of Specter's switching parties, "I have to say I don't think it did our profession any good for someone to announce that he switched parties purely so he could survive."
New polls in January indicated voter support was growing for Toomey, who now held a projected nine percentage point lead over Specter and an eight-point lead over Sestak. Specter continued to lead against Sestak in the Democratic primary poll, this time by a 21-point margin. Some political scientists believed Toomey's gain over Specter could be attributed to voter distrust of establishment candidates and growing dissatisfaction with the health care proposal pending in Congress. However, some Democratic leaders felt Sestak's challenge to Specter was having a detrimental effect not only to Specter but to the Democratic party in general and their prospects for ultimately winning the general election. This feeling was enhanced by the growing national support for the Republican party, and especially by the unexpected victory of the

Specter acknowledged to ''The New York Times'' that the national political mood might work against him in the primary, but insisted he was not discouraged and expressed confidence in his ability to survive.
Race grows more heated
The primary continued to grow more heated in February 2010. On February 5, the two candidates held their first face-to-face debate, and used the 30-minute forum to strongly criticize each other, with Sestak continuing to associate Specter with failed Republican policies and Specter arguing his opponent was more focused on criticizing him than debating policy.
Sestak continued to attack Specter for switching parties, asking, "Is the best the Democrats can do someone who has been on the other side, with respect, for 50 years, and cast 2,000 votes with President Bush?"
Likewise, Specter once again criticized Sestak's missed votes in Congress, which he said would have been enough to earn Sestak a

, which Specter opposed.
The next day, the Pennsylvania Democratic Committee voted to endorse Specter over Sestak, with 77 percent of voters supporting the incumbent Senator, or 229 votes compared to Sestak's 72. Sestak criticized the committee for its decision, but also argued it solidified his own position as a political outsider independent from the mainstream Washington establishment. Media outlets said the vote indicated Specter had convinced most important figures in the state party that he was not simply a crossover politician.
Later in February, Specter accused Sestak of mistreating his employees and disobeying state and federal

T.J. Rooney, a Specter supporter, wrote a letter to Sestak expressing concern about the potential violation of minimum wage laws, which read: "It is inconceivable to me that our standard bearer wouldn’t be paying his workers the minimum wage".
Sestak responded by acknowledging his staff could make more money elsewhere, but said "they choose to work hard and make some sacrifices because they know how important it is to elect someone to the United States Senate who shares their principles".
Specter maintains momentum
As the primary race entered into March, Specter appeared to be maintaining his momentum, with polls indicating he not only led Sestak by 24 percentage points but had recaptured a projected lead against Toomey in the general election by a margin of 49 to 42 percent. Pollsters indicated Specter was still benefiting greatly from his strong name recognition, whereas Sestak and Toomey remained relatively little-known. Peter Brown, assistant director of the Quinnipiac University Polling Institute, said, "There remains no evidence that his primary challenger, Congressman Joe Sestak, has made much progress as we get within three months of the May primary."

noted that while "thus far, Sestak has failed to meet expectations", the poll also indicated some weaknesses for Specter. Namely, more than half of the surveyed Pennsylvanians did not feel he deserved another term. Among Democrats who knew the candidates well enough to form an opinion of both, Sestak led Specter 54 percent to 37 percent.
On March 16, Governor Rendell restated his past support of Specter and said of Sestak, "He has, in my mind, no chance to win."

On March 30, Specter won the backing of the AFL–CIO, which was considered one of the most important endorsements in the primary race.
It was one of several major labor endorsements Specter had received, including the state

'' reporter Colby Itkowitz described as "an obvious effort to show Democrats that he could hold his own in a general election matchup." At the end of the debate, Toomey voiced respect for Sestak and described him as a more principled man than Specter, whom he criticized for not participating in more debates. Later that month, when the Senate candidates publicly released their quarterly campaign finance reports on April 15, it was revealed Toomey raised more in the first three months of 2010 than either Democratic candidate, adding $2.3 million to his total $4.1 million war chest compared to Specter adding $1.1 million to his total $9.1 million fund.
Political analysts attributed this to the national swing in momentum toward Republicans, and said that it could indicate the Republicans would be victorious in many Senate races, including in Pennsylvania.
Sestak raised $442,000 in the three-month period, down from his previous quarter, which Specter's campaign said proved Democratic donors had rejected his candidacy. Specter's fundraising advantage was significant because it allowed him to start early in running political campaign commercials.
Television advertisements
Starting in April, both Specter and Sestak launched television advertisements that were particularly critical of each other. Sestak, who had been saving most of his roughly $5 million campaign funds until the final month of the primary race, unveiled a 60-second spot that highlighted his Navy career and described the role his daughter's experience as a brain cancer survivor played in his decision to enter politics.
The commercial did not discuss Specter by name but made several implicit references to him, such as Sestak's statements that "too many politicians are concerned about keeping their jobs instead of helping people" and "if we want real change in Washington, we can't keep sending the same career politicians to represent us".
Specter launched several commercials, most focusing on his plans to promote job growth. One advertisement, however, focused entirely on attacking Sestak, highlighting not only his voting attendance record – labeling him "No Show Joe"
– but also his Navy service. The commercial stated Sestak was "relieved of duty in the Navy for creating a poor command climate," a reference to Sestak's 2005 transfer from a senior Pentagon planning post to a lesser position, which effectively ended his naval career.

Sestak gains in closing weeks
Sestak and Specter held their first and only televised debate on May 1 at Philadelphia's Fox affiliate. The two candidates bitterly attacked each other's character and honesty.
The two began arguing even before the hour-long debate formally began, when Sestak objected to Specter's use of notes and said that the rules did not allow them. The debate organizer ruled that the notes were allowed.
Specter criticized Sestak for campaign advertisements that accused the Senator of lying about Sestak's record. Specter said, "Nobody has ever called me a liar," and demanded an apology, to which Sestak did not respond. Specter also repeatedly asked Sestak to publicly release his military records, to which Sestak again refused to respond.
Sestak accused Specter of using Republican-style tactics in the vein of

, a former adviser to George W. Bush, and said Specter's attacks were meant to mask his record of supporting Bush's failed economic policies. Specter insisted the questions raised about Sestak's naval record were legitimate because much of Sestak's campaign was based on his military background, adding, "It goes to his ability to get things done, to get along with people. He's all peaches and cream on television."
Specter criticized Sestak for supporting the troop build-up in Afghanistan, while Sestak noted that Specter voted against a ban on assault weapons in the 1990s.
''The Philadelphia Inquirer'' noted the debate was "every bit as contentious as their Democratic Senate primary struggle has become in its closing days".

With only two weeks remaining before the primary, a Quinnipiac University poll released May 4 showed Specter's lead against Sestak had significantly narrowed, dropping from 53 to 32 percent in the previous month to 47–39 percent. A daily tracking poll by Muhlenberg College showed the race as even closer, with Specter supported by 46 percent of likely voters surveyed, and Sestak trailing only four points at 42 percent.
The Quinnipiac poll indicated the strongest factor in these changes was that Sestak was gaining better name recognition due to his television commercials.
According to the poll, 43 percent of respondents now had a favorable view of him, compared to only 33 percent in March.
The day after the poll was released, Sestak unveiled a new television advertisement strongly critical of Specter, highlighting the incumbent Senator's Republican history and showing images of him with George W. Bush and Republican vice presidential candidate

2006 House campaign, endorsed Specter in the Senate race, calling him "fighter and a friend, and I am proud to vouch for his character".
''The Philadelphia Inquirer'' called Sestak "a worthy opponent" and said that his determination made the race especially competitive, but ultimately embraced Specter, whose overall career record the newspaper said was "a good choice for Democrats".

However, despite his long position of support for Specter, Obama did not fly to Pennsylvania to actively campaign for the Senator during the campaign's final days.
As the campaign entered its final week, polls showed Specter and Sestak at a dead heat, with different surveys reporting contradictory findings over which candidate maintained a slight edge. A Quinnipiac University poll found Specter leading 44–42 percent, with fourteen percent undecided. A Franklin & Marshall poll found Sestak ahead 38–36 percent, with about a quarter of voters undecided. In both cases, the lead fell within the survey's margin of error. G. Terry Madonna, director of the Franklin & Marshall poll, said that Sestak improved because his television commercials were resonating with voters on three fronts: the arguments that Specter switched parties for solely political reasons, that he consistently voted for Republican policies and that he had been in office too long.
Polling
Results
Sestak won the May 18 primary with 53.8 percent of the vote, or 568,563 of the votes cast, compared to 46.2 percent and 487,217 votes for Specter.
The defeat led to the end of Specter's nearly 30-year Senate career, the longest of any Pennsylvania Senator in history.
Afterward, Sestak declared, "This is what democracy should look like: a win for the people over the establishment. It should come as no surprise to anyone that people want a change." Specter conceded defeat and said, "It's been a great privilege to serve the people of Pennsylvania. It's been a great privilege to be in the United States Senate."
Commentators suggested Specter's defeat signaled an electorate unsatisfied with the establishment in both major parties, and indicated that the backing of prominent politicians had little effect on voters during this political age.
Sestak's victory was seen as a minor embarrassment for Obama, who strongly and publicly advocated for Specter during the race.
Several news outlets reflected that Sestak's television advertisements condemning Specter as a hypocrite and opportunist were especially effective and may have been the primary factor in his victory.
''The Washington Post'' said the Pennsylvania race drew more attention than any other primary election in 2010 due to Specter's longevity and his switch to the Democratic party.

Clinton job offer to Sestak
During a February 2010 television interview, Sestak said that in July 2009, he was offered a job in President Obama's administration if he dropped out of the race. During a February 18 taping of ''Larry Kane: Voice of Reason'', a Philadelphia-area local news show, host
Larry Kane asked Sestak whether such an offer had been made, to which Sestak responded, "Yes", without elaborating beyond that it was a high-ranking assignment and that he did not plan to take it.
In subsequent press inquiries, Sestak repeatedly stood by his original statement. When asked about the matter by ''The Washington Post'', he said, "There has been some indirect means in which they were trying to offer things if I got out." Likewise, during an appearance on the Fox News Channel, he said, "I was asked a direct question yesterday, and I answered it honestly. There's nothing more to go into. I'm in this race now."
