Democrats face internal ideological divisions as well. Their restored majority comes thanks to many moderate candidates who beat Republicans in districts that voted for Trump. But the party will also welcome newcomers who ran on distinctly progressive agendas, calling for Medicare-for-all or abolishing the Immigration and Customs Enforcement agency. Those lawmakers include New York's Alexandria Ocasio-Cortez, who beat longtime Democrat Joseph Crowley in a June primary, and Michigan's Rashida Tlaib, who is set to claim the seat once held by veteran lawmaker John Conyers Jr. in a deep-blue district.
That mix will be certain to create tensions over the party's priorities, especially with a restive liberal base that has already begun calling for impeachment proceedings against Trump.
Democrats also failed to take over the Senate, leaving the GOP-controlled chamber as a check against Democrats' ability to pass partisan legislation through Congress. That could mean an impasse on issues including immigration, gun regulations and health care.
Democrats picked up the seats they need in large part by targeting suburban districts where Trump had grown increasingly unpopular, through a relentless focus on health care and other economic issues. But their message didn't resonate as widely in rural areas, leaving them short of the massive "blue wave" some in the party had hoped for.
In the eastern suburbs of Denver and in Kansas City and Minneapolis-area districts, GOP incumbents fell to Democratic challengers. All three seats had been heavily targeted by Democrats in 2016, but this year was different.
In northern Virginia, Republican incumbent Barbara Comstock lost to Democrat Jennifer Wexton, while in one surprise win, Democrat Max Rose - a former boxer who raised millions on the strength of a viral video - unseated Rep. Dan Donovan, R-N.Y., in a seat encompassing Staten Island and Queens. Donovan was the only Republican representing New York City.
In a disappointment for the Democrats, incumbent GOP Rep. Garland "Andy" Barr held off a strong challenge from Democrat Amy McGrath, a former fighter pilot. McGrath raised millions in small donations and rocketed into contention thanks to a viral video introducing her candidacy, but her bid fell short in a district where Trump beat Clinton by 15 percentage points.
Heading into Election Day, Republicans had said their best-case scenario after Tuesday's voting was a narrower House GOP majority than the 45-seat margin they now command. Republicans had pledged that, if returned to power in the House, they would get to work on a new 10 percent tax cut for the middle class Trump spoke of in the closing days of the campaign.
"We've known from the beginning that history was not on our side this election cycle. And the big money was not on our side," House Majority Whip Steve Scalise, R-La., said, citing a "motivated base" on the Democratic side who inundated Republican incumbents with small donations to their challengers.
House Republicans also face leadership questions heading into the next Congress, as well as internal ideological differences.
On the GOP side, with House Speaker Paul Ryan of Wisconsin retiring from Congress, Majority Leader Kevin McCarthy of California is his likeliest successor as the top Republican leader in the majority or minority. But he may not get there without a fight, since Scalise is also eyeing the job, and Rep. Jim Jordan of Ohio, a leader of the House Freedom Caucus, is the choice of some conservatives.
Despite the strong economy and Republicans' success in pushing a $1.5 trillion tax cut package into law, those achievements were not central to many GOP campaigns. Instead many Republicans followed Trump's lead in raising fears about illegal immigration and crime, while casting Democrats as overly liberal and linking them to Pelosi.
"We've got to get down to work as soon as we are sworn in on Jan. 3 and make some real change come about. ... we're going to have a lot of brand new members -- many of whom will come from tough districts, many of them that never served in any elected office in their higher lives."
