In one of the nation's most expensive open seat contests this election year, Republican Sean Duffy has taken the seat held by retiring Rep. David Obey (D-Wis.) for some 40 years.
Duffy defeated Democrat Julie Lassa Tuesday in a race that attracted millions of dollars in spending from both the NRCC and DCCC, as well as conservative-leaning outside groups.
Freshman Rep. Mark Schauer (D-Mich.) lost to former Rep. Tim Walberg (R). Schauer won the GOP-leaning seat in the 2008 Dem wave.
Cory Gardner, a state lawmaker, has unseated freshman Democratic Rep.
Betsy Markey to take the state's conservative-leaning Fourth District,
which occupies the eastern quarter of the state.
Markey had won her seat in 2008 with 56 percent of
the vote, but her support for the Democrats' health reform law and
economic stimulus bill proved unpopular with voters in the district,
where there are 40,000 more registered Republicans than Democrats.
Republicans kept Rep. Mark Kirk's (R-Ill.) seat, a district Democrats were expected to win. Republican Robert Dold beat Democrat Daniel Seals. Kirk won President Obama's former Senate seat.
Republican Rick Crawford captured the seat of retiring Rep. Marion Berry (D-Ark.) Tuesday.
Rep. John Hall (D-N.Y.) lost his reelection bid Tuesday. The sophomore Democrat was defeated by Republican Nan Hayworth.
vulnerable New York Democrat, Rep. Michael Arcuri, also lost. The
freshman lawmaker was defeated by Republican Richard Hanna.
Longtime Rep. and Chairman of the House Armed Services Committee Ike Skelton (D-Mo.) has lost his reelection bid to Republican Vicky Hartzler.
Skelton is the second prominent Democratic Committee Chairman to lose Tuesday. House Budget Committee Chairman John Spratt (D-S.C.) lost his reelection bid as well.
Another two prominent subcommittee chairmen lost their bids for reelection Tuesday--Rep. Chet Edwards (D-Texas), who chaired the Appropriations subcommittee and Rep. Rick Boucher (D-Va.), who chaired the subcommittee on Energy and Commerce.
Former Rep. Charlie Bass (R-N.H.) has retaken his old House seat. Bass
defeated Democrat Ann McLane Kuster, a favorite of liberal groups, to
represent New Hampshire's second district once again.
In one of the night's biggest upsets so far, Rep. Bob Etheridge (D-N.C.) was defeated by Republican challenger Renee Ellmers.
Etheridge's race gained some brief national attention earlier this year after a video of the congressman in a confrontation with two students hit YouTube.
Former Alaska Gov. Sarah Palin endorsed Ellmers in August and the race made national news again in September when the Republican released a campaign ad labeling the proposed Islamic cultural center and mosque near Ground Zero in New York, a "victory mosque."
Republican Tom Reed has won former Rep. Eric Massa's (D-N.Y.) seat.
Massa resigned earlier this year after facing allegations of acting
inappropriately with his staff. Reed beat Democrat Matt Zeller to take
