In May 2018, President Trump began to emphasize his effort to overcome the traditional strength of the non-presidential party in midterm elections, with the "top priority for the White House eing to holdthe Republican majority in the Senate".

In late August 2018, the ''Huffington Post'' reported that Trump and his administration had been engaging in campaign activity on taxpayer-funded trips. According to the report, a top White House staffer identified 35 events by Cabinet and senior staff members "with or affecting House districts in August already". White House Deputy Press Secretary Lindsay Walters called the report "misleading".
The 2018 elections featured a wider range and larger number of campaign advertisements than past midterm elections. Almost a third of Republican ads focused on taxes, especially on the recently enacted

According to ''The Washington Post'', President Trump "settled on a strategy of fear—laced with falsehoods and racially tinged rhetoric—to help lift his party to victory in the coming midterms, part of a broader effort to energize Republican voters". In November 2018, Facebook, NBC, and Fox News withdrew a controversial pro-Trump advertisement that focused on a migrant caravan; Facebook noted that the ad violated Facebook's rules concerning "sensational content".
Nearly half of all advertisements by Democrats focused on health care, in particular on defending the

Three Republican incumbents did not seek election in 2018 while all Democratic and independent incumbents sought another term. 42 Republican senators and 23 Democratic senators were not up for election.

. Democrats won the nationwide popular vote for the House of Representatives by 8.6 percentage points, one of the highest margins won by either party since 1992. Due in part to the surge in turnout, the total number of votes won by Democratic candidates for the House of Representatives nearly equaled the number of votes Trump won in the 2016 presidential election. The 2018 elections were the third midterm elections since 2006 in which the President's party lost control of the House of Representatives.
Democrats defeated 29 Republican incumbents and picked up 14 open seats. Republicans did not defeat a single Democratic incumbent, though the party did pick up two open seats in Minnesota and one in Pennsylvania. Republicans defended the vast majority of their rural seats, but several urban and suburban seats flipped to the Democrats. Many of the districts picked up by Democrats had given a majority or a plurality of their vote to Hillary Clinton in the 2016 presidential election. Of the 447 individuals who served in the House during the 115th Congress, at least 104 did not win re-election in 2018—this represents the third-highest turnover rate of any election cycle since 1974.
Special elections
There were a total of eight special elections to the United States House of Representatives in 2018. These elections were held to fill vacancies for the remainder of the 115th Congress. As a result of the special elections held prior to November 6, Democrats won a net gain of one seat.

. Democrats defended every seat they had controlled prior to the election and picked up seven governorships. They won open seats in Michigan, Nevada, Kansas, New Mexico and Maine and defeated Republican incumbents in Illinois and Wisconsin. They also picked up the independent-held seat in the U.S. Virgin Islands in a runoff election held November 20, 2018. Most of the Democratic victories were in Democratic-leaning states or swing states. Democratic candidates ran well ahead of Hillary Clinton in South Dakota, Oklahoma, Idaho, South Carolina and other " red states" that had given large margins to Trump in the 2016 presidential. All of those candidates fell short, however, and Kansas was the lone red state to elect a Democratic governor in 2018.
Republicans picked up the independent-held seat in Alaska, and Republican incumbents won election in competitive and Democratic-leaning states such as Arizona, Iowa, Massachusetts, Vermont, New Hampshire and Maryland. The party also won competitive open seat elections held in Florida, Georgia and Ohio. Democrats picked up the governorship of Guam, but the incumbent Republican governor of the Northern Marianas Islands won re-election.

All parties presented candidates in more races than usual. The number of Democratic candidates increased to almost 88% of the races in 2018 from 77% in 2014. Parties often do not run in races where the incumbent or other favorite candidate has a very high margin in polls, in order to focus resources on more competitive races with greater chances of success; however, increasing the number of candidates is seen as a way to drive local voter engagement and increase the number of votes for other, more competitive races at an upper level.

attributed the continuing Republican dominance of state legislatures in part to Republican control of redistricting in many states following 2010. In at least three states (Pennsylvania, North Carolina, and Michigan), Republicans retained control of the lower house even though a majority of voters voted for a Democratic candidate for the lower house. In many states, Democrats indicated their hope that 2018 would be part of a "two-cycle process", with gains in 2018 putting the party within distance of taking control of more state legislative chambers in the

In 2019, Special Counsel Robert Mueller's investigation on Russian interference in the 2016 election concluded "at least one Florida county" was successfully penetrated, and Governor Ron DeSantis said voter databases in two counties had been successfully penetrated.
On December 22, 2018, Coats reported that there was no evidence of vote tampering, but that "influence operations" had persisted. "The activity we did see was consistent with what we shared in the weeks leading up to the election. Russia, and other foreign countries, including China and Iran, conducted influence activities and messaging campaigns targeted at the United States to promote their strategic interests". That same month, ''Politico'' reported that the

Aftermath and reactions
The Democratic takeover of the House of Representatives gave the Democratic Party the ability to block Republican legislation in the 116th United States Congress, which met from January 2019 to January 2021. The takeover also gave the Democrats control of congressional committees, along with the accompanying power to issue

s and conduct investigations. Continued Republican control of the Senate gave the Republican Party the opportunity to confirm President Trump's nominees without Democratic support. During the 116th Congress, the Republican-controlled Senate confirmed numerous Trump-appointed judges.
After the election, despite the Democratic takeover of the House, President Trump claimed he had won a "big victory". He indicated that he looked forward to "a beautiful bipartisan-type situation" but promised to assume a "warlike posture" if House Democrats launched investigations as attacks on his administration. House Minority Leader Nancy Pelosi asserted that her party won gains because of voter desire to "

said election day was "a very good day" for his party.
The election was widely characterized as a " blue wave" election. At the end of election night, Democratic gains in the House appeared modest and the Democratic candidates trailed in Senate races in Arizona and Montana and looked set to make a net loss of as many as four Senate seats, leading some news outlets to characterize the election as a "split decision" whereas other outlets described it as a "blue wave". However, late ballot counting over the next days and weeks found Democrats winning several more seats in the House and the Arizona and Montana Senate elections, leading to a re-evaluation of the initial election night analyses. One week after the election, Nathaniel Rakich of ''

'' said the election was "by any historical standard, a blue wave". Two weeks after the election, Nate Silver of ''FiveThirtyEight'' wrote: "There shouldn't be much question about whether 2018 was a wave election. Of course it was a wave". It was third-largest midterm change of seats for either party in the House in the post-Watergate era, and the largest Democratic House gain since 1974. In Ohio and North Carolina, Democrats failed to pick up a single seat despite winning close to half the vote. While Democrats won almost half the vote in Ohio, they only won a quarter of its House elections. ''The New York Times'' asserted that gerrymandering affected the outcomes of races in those states. Democrats also made among the largest gains in House seats in Pennsylvania, where the state Supreme Court had struck down a heavily gerrymandered map that favored Republicans.
Research has found that Republicans who voted for the repeal of the Affordable Care Act got lower vote shares in the 2018 election. Studies also show that Trump's implementation of tariffs that adversely affected the U.S. economy adversely affected Republican outcomes in the 2018 election.
