in 2009. The state's primary election occurred on September 14, 2010. Republican U.S. Representative and former Governor Mike Castle was believed to be heavily favored to win both the primary and the general election. However, Castle was upset by Christine O'Donnell in a primary contest that had national visibility. During the general election campaign, O'Donnell, a Tea Party candidate, drew media attention for making several false claims and gaffes, as well as an unusual campaign ad in which she denied that she was a witch. In the general election, O'Donnell lost to Democratic nominee

Campaign

In April 2009, Representative Mike Castle stated, "there's probably a better chance I'll run for the Senate than the House. utI said there's a chance I won't run at all." On October 6, 2009, Castle announced that he would in fact run for the Senate seat. After her 2008 loss to Biden, Christine O'Donnell had indicated she would strongly consider running for the seat again in 2010, asking supporters on her website to "save your yard sign!!" On February 12, 2009, O'Donnell had announced her candidacy. She reiterated that she was in the race even after Castle announced his candidacy in October 2009, and formally launched her campaign on March 10, 2010. In her remarks, O'Donnell criticized excessive government spending, said that Castle was the most liberal Republican in the House, and said that the

'' in March 2010 detailed O'Donnell's fiscal difficulties, she attributed the problems to misunderstandings and errors, and said, "I think the fact that I have struggled financially is what makes me so sympathetic." Nevertheless, her financial problems became a focal point of establishment Republican attacks against her. A July 2010 Rasmussen Reports poll showed O'Donnell running ahead of Democratic Senate candidate

. The Tea Party Express said it might spend as much as $600,000 backing O'Donnell. The added buzz about her campaign and the possibility that another establishment Republican figure might be defeated by an insurgent brought national attention to the race. The same attention also brought additional scrutiny on her record and financial history, including a contentious interview on WGMD radio. She had claimed that she beat or tied Joe Biden in two of the state's three counties in their 2008 campaign. Later, she admitted this was inaccurate, and that she had lost all three counties. As September began, the tone of the race grew nastier, with

chair Tom Ross saying, "Is Christine O'Donnell actually this unhinged from reality? Or is she simply a liar, whose total lack of respect for Delaware voters leads her to deliberately and repeatedly deny the clear facts surrounding her many personal and professional failures?" Ross also said, "She's not a viable candidate for any office in the state of Delaware. She could not be elected dog catcher." The O'Donnell campaign generated controversy in early September when a political consulting firm hired by O'Donnell released a web video insinuating that her opponent Castle was having a gay affair. O'Donnell quickly distanced herself from the claims, pointing out that the firm in question was no longer working for her campaign, though the manner in which she denied involvement in the rumor led some to suspect that she was intentionally engaging in a

As O'Donnell's manager, I found out she was living on campaign donations - using them for rent and personal expenses, while leaving her workers unpaid and piling up thousands in debt. She wasn't concerned about conservative causes. O'Donnell just wanted to make a buck." O'Donnell denied most of what Murray said and stated that she had fired Murray. With days to go before the primary, O'Donnell was bolstered by an endorsement from former

. Castle was considered the favorite to prevail in the general election. Polls that considered a matchup of Castle against Democrat Chris Coons indicated that Castle would defeat Coons by a significant margin. In September, a poll by Public Policy Polling showed Castle leading Coons by a 10-point margin. However, on September 14, O'Donnell won an upset victory over Castle in the Republican primary. O'Donnell was considered far less electable in a general election than Castle; ''Politico'' reported, "The path to a Republican Senate takeover narrowed to the point of vanishing Tuesday night, as marketing consultant Christine O’Donnell upset Rep. Mike Castle in Delaware’s Senate primary and likely dashed the GOP’s hopes of capturing the seat in the process".
