U.S. House races that have been called by the Associated Press so far:

Arkansas : Tim Cotton (R)

Republicans gained a House seat here with the victory of Tom Cotton over state Sen. Gene Jeffress (D) in the largely rural 4th District. The AP also projected reelection for the state’s three Republican incumbents, painting Arkansas a solid red.

Deleware : Rep. John C. Carney Jr. (D)

Democrat John C. Carney Jr., the state’s sole representative in the House, has easily won reelection, defeating Republican Thomas Kovach and two independent challengers. Carney received more than 72 percent of the vote with about 60 percent of the state’s precincts reporting.

Georgia : Doug Collins (R); five Democratic incumbents reelected

A Republican, Doug Collins, has won a new, fourteenth House seat that Georgia gained through redistricting, according to the AP. However, Republicans otherwise failed in their bid to increase their House majority in Georgia, as all five Democratic incumbents were reelected (along with all eight GOP incumbents).

Among the Democratic victors was Rep. John Barrow, the last white Democratic congressman from the Deep South. Barrow’s 12th District seat had been in jeopardy due to redistricting. His Republican challenger, State Rep. Lee Anderson, benefitted from $3.5 million in spending by outside groups. But Anderson won the GOP nomination by just 159 votes in a bruising primary that required a runoff election. And Barrow, a Blue Dog Democrat who has made a point of distancing himself from his party by voting against Obama’s health-care law, defeated Anderson by more than seven percentage points, according to the AP.

Illinois : Rep. Jesse L. Jackson, Jr. (D); Tammy Duckworth;

Democrats picked up four seats in the state’s congressional delegation, giving the party a 11-7 edge thanks in part to redistricting by the Democratic-controlled legislature. Among the victors was Tammy Duckworth, an Army veteran who lost both legs from injuries she sustained in a blast in Iraq. She beat freshman Joe Walsh, a Tea Party Republican elected in a GOP wave two years ago.

Rep. Jesse L. Jackson, Jr., a Democrat representing the Second District encompassing Chicago and its suburbs, handily fended off two challengers despite running an anemic campaign since his hospitalization and leave of absence from Congress because of mental health issues.

Kentucky : Andy Barr (R); Rep. John Yarmuth (D); Thomas Massie (R)

Rep. Ben Chandler (D) was defeated by Republican lawyer Andy Barr, who sought to portray the incumbent — a “Blue Dog Democrat” who voted against Obama’s health care bill — as an ally of the deeply unpopular president. In the 3rd District, Rep. John Yarmuth (D) was aided by favorable redistricting on the way to his fourth consecutive victory, according to the AP: Yarmuth defeated Republican financial adviser Brooks Wicker.

The AP has also called the race for the 4th District seat previously occupied by Rep. Geoff Davis (R), who retired this summer.

Republican Thomas Massie, an engineer who founded a tech company before moving home to Kentucky to live on a farm, defeated Democrat William Adkins, a coal miner turned lawyer.

The state’s three Republican incumbents cruised to reelection, according to the AP.

Louisana : Rep. Charles Boustany (R) and Rep. Jeff Landry (R) to face run-off

Also as expected, Louisiana's House delegation — which shrank from seven seats to six due to decennial redistricting — will continue to be dominated by Republicans, as four GOP incumbents sailed to victory. However, while the lone Democratic incumbent, Rep. Cedric Richmond, appeared to be leading with just over half of the vote, it was too close to call the contest for his 2nd District seat as of late Tuesday with more than 90 percent of precincts reporting, according to the AP.

It also appeared that two Republican incumbents who were running against each other because their districts have been merged — Rep. Charles Boustany and Rep. Jeff Landry — will face a run-off next month. That’s because under Louisiana’s unusual “jungle primary” system, all candidates for congressional office, including those of the same party, must run on the day of the general election. Unless one wins an outright majority, the top two vote-getters must square off on Dec. 8.

Boustany, a party elder who had the advantage because three-fourths of the residents of the newly drawn third district are his current constituents, was leading with about 45 percent of the vote, with all precincts reporting, according to the AP.

Landry, a tea party conservative considered more of a GOP outsider had 30 percent of the vote.

Maryland : John K. Delaney (D)

Democratic challenger John K. Delaney defeated Rep. Roscoe G. Bartlett on Tuesday, taking advantage of his great personal wealth and a redrawn district to defeat the 10-term Republican congressman.

Delaney, a Potomac businessman, led Bartlett 58 percent to 39 percent in a district now stuffed with Montgomery County Democrats. But he also cast himself as a moderate Democrat whose ability to cut a deal in the world of finance would help him reach across the aisle in Congress.

His victory allowed the party to snatch a seat that used to be safe for Republicans and chip away at the GOP’s 25-seat gap in the House.

Massachusetts : Joseph P. Kennedy III (D); Ed Markey (D); Niki Tsongas (D)

Congress once more has a Kennedy in it. Joseph P. Kennedy III, 32, was the winner in the 4th congressional district, beating Sean Bielat, a businessman and Marine reservist. Kennedy, who fills the seat vacated by Barney Frank, was an assistant district attorney. His father, also named Joseph, is a former congressman and the son of the late Robert F. Kennedy. Democrats won in eight of the Bay State’s nine congressional districts. Among them are Ed Markey (5th District) and Niki Tsongas (3d District), widow of former senator and congressman Paul Tsongas. In two districts there was no Republican opposition.

Mississippi : All four incumbents re-elected

The party balance of Mississippi’s Congressional delegation was unchanged, with voters re-electing all four incumbents—including three Republicans and one Democrat—according to the Associated Press. These include freshman Republican Steven Palazzo, who unseated Democrat Gene Taylor in 2010, and who benefitted fromTaylor’s decision not to attempt a comeback.

New Jersey : Rep. Bill Pascrell Jr. (D); Rep. Jon Runya (R)

In the new 9th District, Rep. Bill Pascrell Jr. beat his Republican challenger Shmuley Boteach, according to the Associated Press. Pascrell fought a tough race in the June primary, defeating Steven R. Rothman by a large margin in an expensive Democratic primary for the newly drawn district.

In the most closely watched House race in the state, first-term Republican Rep. Jon Runyan in the 3rd District won reelection, fighting off Democratic challenger Shelley Adler, the widow of his 2010 opponent. Runyan, a former Philadelphia Eagles offensive tackle, was favored to win but it was a tough and sometimes nasty race.

Rhode Island : Rep. Jim Langevin (D)

Incumbent Rep. Jim Langevin (D) coasted to victory as representative of Rhode Island’s 2nd congressional District. He defeated Republican challenger Michael Riley.

Utah : Rep. Jason Chaffetz (R)

Republican Jason Chaffetz, who serves on the House Committee on Oversight and Government Reform, has won reelection over Democrat Soren Simonsen, the AP projected. Chaffetz had 73 percent of the vote with two percent of precincts reporting.

Vermont :Rep. Peter Welch(D)

Rep. Peter Welch (D) coasted to victory as the state’s at-large representative, defeating Republican challenger Mark Donka. Donka was a severly underfunded candidate; he didn’t meet the $5,000 fundraising threshold that would have required a campaign finance report in September. Welch, who was elected to the House in 2006, raised over $1 million for the race.

Virginia : Rep. Scott Rigell (R); Majority Leader Eric Cantor (D)

Results of Tuesday’s election leave Republicans with an 8-3 advantage over Democrats in the state’s House of Representatives delegation. The sweep by incumbents stands in stark contrast to the last two congressional elections in Virginia. In 2008, Democrats rode Barack Obama’s coattails to pick up three seats and gain a one-seat edge. In the midterm election two years later, Republicans gained three seats to re-establish their 8-3 advantage.
