Trump, who took an active role in recruiting Republican candidates for Congress and is strongly hinting at a third run for the presidency in 2024, had mixed results.
He notched a victory in Ohio, where author J.D. Vance won a Senate seat to keep it in Republican hands. But television host and heart surgeon Mehmet Oz failed to win his Pennsylvania Senate race.
Trump allies also were struggling in Arizona, Georgia and Nevada Senate races, where ballots were still being counted.
Meanwhile, Florida Governor Ron DeSantis, who could be a main Republican challenger to Trump in 2024, added to his growing national profile, defeating Democratic challenger Charlie Crist by nearly 20 percentage points, Edison projected.
Voter anger over the Supreme Court's June decision to overturn the nationwide right to abortion helped Democrats to curb their losses.
SENATE A TOSS-UP
The Senate was still a toss-up, with the pivotal battles in Arizona, Georgia and Nevada still in play. The Georgia Senate race could end up in a December 6 runoff, possibly with Senate control at stake.
Democrats currently control the 50-50 Senate with Vice President Kamala Harris able to break any ties.
Thirty-five Senate seats, all 435 House seats and three dozen governors' races were on the ballot.
More than 46 million Americans voted ahead of Election Day, either by mail or in person, according to data from the US Election Project, and state election officials caution that counting those ballots will take time.
High inflation and abortion rights were voters' top concerns, exit polls showed. Crime, a major focus in Republican messaging in the campaign's final weeks, also was a top issue.
COMPETITIVE DISTRICTS
In a possibly embarrassing defeat for House Democrats, Representative Sean Maloney narrowly trailed a Republican challenger in his bid for a sixth term.
Maloney chairs the Democratic campaign committee charged with electing more Democrats to the House. His was one of a couple of races in New York state where Republicans were performing better than expected.
Both parties notched victories in competitive districts.
Local officials reported isolated problems across the country, including a paper shortage in a Pennsylvania county. In Maricopa County, Arizona -- a key battleground -- a judge rejected a Republican request to extend voting hours after some tabulation machines malfunctioned.
The problems stoked evidence-free claims among Trump and his supporters that the failures were deliberate.
Scores of Republican candidates have echoed Trump's false claims that his 2020 loss to Biden was due to widespread fraud, raising fears among Democrats that they could interfere with the 2024 presidential race.
In Pennsylvania, Republican gubernatorial candidate Doug Mastriano, who sought to overturn the state's election results after Trump lost, was defeated by Democrat Josh Shapiro. Democratic governors also fended off strong Republican challenges in Michigan and Wisconsin, two states likely to remain political battlegrounds in the 2024 presidential race.
The primary issue weighing on Democrats was stubbornly high annual inflation, which at 8.2 percent stands at the highest rate in 40 years.
Voters in California, Michigan and Vermont approved referendums enshrining abortion rights in their state constitutions. Deeply conservative Kentucky looked poised to reject a constitutional amendment that would have declared there was no right to abortion.
