Democrats pulled off a series of early Election Night victories in their quest to keep control of the Senate, while Republicans kept control of the House.
Thirty-three Senate seats are up for grabs, but 10 hotly-contested ones were expected to decide the race.
With polls closed across most of the country, Fox News projected Democratic victories in many of the key Senate races, including for challenger Elizabeth Warren over Republican Sen. Scott Brown in Massachusetts and incumbent Sen. Claire McCaskill over Republican challenger Rep. Todd Akin in Missouri.
Democrats fell short of their goal of picking up 25 House seats, which would have given them control of the 435-member legislative chamber.
Fox News projects House Majority Leader Eric Cantor will defeat Democratic challenger Wayne Powell to serve a seventh term in Virginia’s 7th District. And there are indications that Republicans may pick up seats.
“I’m humbled to be trusted by Americans,” said House Speaker John Boehner, R-Ohio. “We will never let you down.”
In other Senate races, Fox News projects Democratic Rep. Chris Murphy will be the winner in his race against Republican Linda McMahon for the seat left open by retiring independent Sen. Joe Lieberman.
In addition, Indiana Democrat Joe Donnelly is projected to defeat Republican Richard Mourdock for the seat of long-time Republican Sen. Richard Lugar.
Mourdock upset Lugar in the Republican primary but has struggled in the general election after making comments on rape and abortion that Democrats have used against him.
If Democratic Senate incumbents on the West Coast hold their seats tonight, as expected, this means the U.S. Senate will remain in Democratic hands.
There are 23 Democrats and 10 Republicans up for re-election in the Senate. Democrats now control the Senate, 53-47.
In Florida, Democratic Sen. Bill Nelson won a third term, defeating Republican Rep. Connie Mack.
Fox News also has projected that Democratic incumbent Bob Casey will hold on to win in the Senate race in Pennsylvania. The first-term senator will defeat Republican challenger Tom Smith.
The open Senate seat in Maine will be filled by independent candidate Angus King, who beats out Democrat Cynthia Dill and Republican Charlie Summers to take over the seat being vacated by retiring Senator Olympia Snowe, a Republican.
King is expected to caucus as a Democrat but hasn’t officially announced that.
In Virginia, the race between Democrat Tim Kaine and Republican George Allen, is still too close to call. The former governors are running for the open seat of outgoing Democratic Sen. Jim Webb.
Fox News projects that liberal Vermont Sen. Bernie Sanders, an Independent who caucuses with the Democrats, will turn back a challenge by Republican John MacGovern.
Fox News also projects that in West Virginia, Sen. Joe Manchin, a Democrat who has distanced himself from Obama’s restrictive coal regulations, will defeat Republican challenger John Raese.
The Ohio Senate race, in which Democratic Sen. Sherrod Brown is dueling with Republican Josh Mandel, also is too close to call.
