House races

In one of the first suprises of the night, Republicans picked up Rep. Rick Boucher's (D-Va.) seat. Republican Morgan Griffiths, the Virginia House majority leader, managed to unseat Boucher, who has held his office since 1983, by focusing his campaign on the Democrat’s vote for the cap-and-trade energy bill. The 9th District is home to a heavy coal industry, which Griffiths contended would stand to lose money under the legislation.

And Republican Robert Hurt won election to Virginia’s 5th District unseating Rep. Tom Perriello (D-Va.) in one of the country’s most highly contested races. President Obama tried to boost Perriello’s standing last Friday with a rally in his hometown of Charlottesville — a move seen by some as risky due to Sen. John McCain (R-Ariz.) gaining the support of the district in 2008’s presidential election.

Rep. Suzanne Kosmas (D-Fla.), who cast an early vote against healthcare before switching to vote in favor of the final version of the bill, lost her reelection bid Tuesday by a sizable margin.  

Republican Sandy Adams was pulling in more than 60 percent of the vote against Kosmas when the race was called.   

Several embattled Democrats fall into the same category as Kosmas on Tuesday, including longtime Rep. Allen Boyd (D-Fla.), Rep. John Boccieri (D-Ohio) and Rep. Betsy Markey (D-Colo.). 

All three also cast votes against the initial version of the healthcare bill before voting in favor of the final measure after heavy lobbying from the Democratic leadership in the House.  

Targeted by Republicans during the campaign, Rep. John Yarmuth (D-Ky.) survived to win reelection to the House Tuesday.

Democrat John Carney won election to Delaware's lone House seat Tuesday, an expected pick-up for the party.

That seat was held by the retiring Rep. Mike Castle (R-Del.) who lost to Christine O'Donnell in the state's Senate GOP primary earlier this year.

House Republican Whip Eric Cantor (R-Va.) won reelection, as expected. If Republicans win control of the House, Cantor could become the next majority leader.

Rep. Mario Diaz-Balart (R-Fla.) won the seat once held by his brother Lincoln Diaz-Balart (R) Tuesday, as was expected. Lincoln Diaz-Balart announced his retirement earlier this year, and his brother opted to run in his district, which leans more Republican.

Also, Rep. Tom Graves (R-Ga.) won reelection Tuesday. He came to Congress earlier this year after winning a special election when Rep. Nathan Deal (R-Ga.) left to run for governor.

Republican Todd Rokita has won retiring Rep. Steve Buyer's (R-Ind.). That makes Rokita the first freshman member elected to the 112th Congress.

It also means Indiana's 4th congressional district stays in GOP hands.

Rep. Hal Rogers (R-Ky.) won reelection to the House Tuesday.

Along with Rep. Jerry Lewis (R-Calif.), Rogers is in the running to be the next chairman of the House Appropriations Committee if Republicans can take control.

Polls have closed in Indiana and GOP Reps. Dan Burton and Mike Pence have been declared the winners in their respective House races.

Neither incumbent faced a tough challenge, so the results are not surprising. Burton survived a tough primary challenge earlier this year.

Other House races to watch in that state: Reps. Baron Hill and Joe Donnelly — both Dems — are in tough reelection campaigns.

The Senate seat that is now in Dem hands is also up for grabs, and Republican Dan Coats is expected to win.

Next round of poll closings is at 7 p.m. ET.

A key endangered Democratic incumbent admitted Tuesday that "turnout isn’t where we need it to be" if he's to win reelection.

Rep. Steve Kagen's (D-Wis.) campaign manager e-mailed supporters to warn them that turnout numbers were flagging and that they needed more voters to make their way to the polls.

"We have just been going over the morning voting numbers — and turnout isn’t where we need it to be in our strong areas," campaign manager Julie Heun wrote in an e-mail. "This race is going to be a squeaker — and every vote will count."

Kagen's facing a tough reelection race in Wisconsin's 8th congressional district against GOP candidate Reid Ribble. Republicans need the seat if they want to pick up the net gain of 39 or more seats they need to win back the House.
