Senate races that have been called by the Associated Press so far:

Connecticut : Rep. Chris Murphy (D)

Democratic Rep. Chris Murphy beat former WWE executive Linda McMahon in Connecticut’s Senate race. The Republican businesswoman self-funded tens of millions of dollars for her second straight Senate race in a row. This cycle, she had a fighting chance. But the fundamentals always favored Murphy in this blue state. 

Florida : Bill Nelson (D)

Sen. Bill Nelson (D) turned back a challenge from Rep. Connie Mack (R) in Florida. The race was called shortly after polls closed; while Nelson looked vulnerable early on in the cycle, this race never became very competitive. 

Indiana : Joe Donnelly (D)

Rep. Joe Donnelly (D) has beaten former congressman Richard Mourdock (R) in the race for Indiana’s open Senate seat. Mourdock beat Sen. Dick Lugar (R) in a primary earlier this year. Since his controversial comments about rape and pregnancy during a late October debate, Mourdock has been a slight underdog despite the state’s Republican lean – significantly narrowing Republicans’ chances at retaking the majority in the Senate. The conservative Mourdock was also hurt by Lugar’s refusal to involve himself in the campaign, making it easier for Democrats to peel off some of the veteran senator’s supporters. 

Maine : Angus King (I)

Former Maine governor Angus King, an independent, is the winner of the state’s open Senate seat. Now that King has apparently been elected to the Senate, questions will persist about whether he will caucus with Democrats. Despite steadfastly refusing to pick a party to caucus with during the campaign, national Democrats and Democratic-leaning outside groups dumped millions into the race to ward off a win by Republican Secretary of State Charlie Summers when the polls narrowed.

Massachusetts : Elizabeth Warren

Sen. Scott Brown (R-Mass.) was defeated by challenger Elizabeth Warren (D) in one of the most expensive and high-profile races of the cycle. 

Brown took his seat in a 2010 special election, replacing the late Sen. Edward M. Kennedy, a liberal icon. Despite the Bay State’s overwhelmingly Democratic electorate, Brown’s personal likability and success in branding himself as a down-to-earth independent made this a tough race. But Warren successfully tied Brown to the national GOP brand while beating back attacks on her character.

Michigan : Sen. Debbie Stabenow (D)

Michigan Sen. Debbie Stabenow (D) has beaten back Republican challenger Pete Hoekstra. Republicanstargeted Stabenowearly in the cycle but failed to mount a strong challenge in the Wolverine State. Hoekstra’s first campaign ad was met with charges of racial insensitivity, an apparent blow to the former congressman’s campaign. He struggled to compete infundraising and never caught up to Stabenow in polls. 

Mississippi : Roger Wicker (R)

Missouri : Sen Claire McCaskill

Missouri Sen. Claire McCaskill (D) beat Rep. Todd Akin (R) in a race that gained national notoriety thanks to the Republican challenger’s comments on pregnancy and rape.  

McCaskill was considered one of the most vulnerable Democrats up for reelection this year. But the social conservative Akin’s primary victory — followed by hiscontroversial comments and refusal to drop out of the race — helped McCaskill keep her seat despite Missouri’s increasingly conservative leaning. 

Ohio : Sen Sherrod Brown (D)

Sen. Sherrod Brown (D-Ohio) has defeated state Treasurer Josh Mandel (R). Republicans were initially enthusiastic about this contest, and Mandel proved himself a prodigious fundraiser. The young Iraq war veteran did have a chance, but this race has been a long-shot for Republicans for a while, particularly as President Obama’s numbers in the state improved. 

Republican groups spent more than $20 millionagainst Brown – more money than the organizations have collectively spent in any other Senate race.

Pennsylvania : Sen. Bob Casey (D)

Sen. Bob Casey (D) has beaten back a challenge from Republican Tom Smith in Pennsylvania. Smith appeared to have an outside chance at pulling an upset here. Although Casey always led in polls, the senator found himself in a closer-than-expected race and was outspent by the wealthy self-funder Smith. (The former coal-mining magnate poured about $17 million into the race.) But Casey responded, and he got help from a Democratic super PAC.

Tennessee : Sen. Bob Corker (R)

Texas : Ted Cruz (R)

Tea-Party-backed Republican Ted Cruz has won the Texas Senate seat, making him the third Hispanic member of the Senate.

Virginia : Tim Kaine (D) 

Former senator George Allen (R) has conceded to former Virginia governor Tim Kaine (D) in the race for the seat being vacated by retiring Sen. Jim Webb (D). The Washington Post has called this race for Kaine. 

“We haven’t succeeded,” Allen told Republicans gathered at Richmond’s Omni hotel for an election night party. ”Tonight after a very hard fought contest, we’re reminded how closely divided we are.”

He noted that both he and Kaine will now have served as both senator and governor. 

Wyoming : Sen John Barrasso (R)
