Democratic businessman Jim Graves has conceded to GOP U.S. Rep. and tea party favorite Michele Bachmann in Minnesota's tight 6th District race.
Graves says he called Bachmann on Wednesday morning to congratulate her on her victory. He says he wishes Bachmann and her family the very best.
Bachmann said in Twitter post it was a hard-fought campaign, and she's ready to get back to work for her district.
Graves sought to persuade voters to choose a successful businessman rather than Bachmann and her controversial national profile. Bachmann hung on to a district that became more Republican through redistricting, but her margin of victory was just over 4,200 votes.
The race was hugely expensive as Bachmann fell back on a fundraising machine that drew from her national following.
Meanwhile, Democrat Rick Nolan upset incumbent Chip Cravaack in northeastern Minn. early Wednesday morning in a race that remained too close too call most of the night.
Nolan was declared the winner just before 1:30 a.m. with 53 percent of the vote. He now has 55 percent of the vote with 96 percent of the precincts reporting. The victory sends Nolan back to Congress after a 32 years absence.
With a look at other races across the state congressional incumbents, Reps. Tim Walz (D), John Kline (R), Erik Paulsen (R), Betty McCollum (D), Keith Ellison (D) and Collin Peterson (D) all handily won re-election in their districts.
Democratic Sen. Amy Klobuchar also won a second term. She was projected the winner just minutes after the polls closed at 8 p.m. She beat state Rep. Kurt Bills and a third-party candidate in a race that was never seen as close.
Klobuchar's popularity, name recognition and big campaign fund kept big-name Republicans from stepping forward to challenge her.
