When much of the nation went to sleep on Tuesday night, the race for Minnesota's 6th district was still too close to call. This morning, multiple sources are reporting that incumbent Rep. Michele Bachmann has narrowly been reelected for a fourth term.

A recount seemed likely late Tuesday, with DFL challenger Jim Graves trailing by less than 1,000 votes, according to the Star Tribune. As final results arrived, the margin widened to about 4,200 votes. With all precincts reporting, Bachmann took 50.49 percent of the vote and Graves took 49.41 percent.

Bachmann declared victory via Twitter at 4:30 a.m. and Graves conceded the race several hours later.

The victory comes after an unexpectedly close race. Graves, a business man and political newcomer, has held is own against Bachmann's national notoriety and $23 million campaign, which Politico notes is among the largest of any House member. The Tea Party favorite received a fundraising boost following her presidential run.

Graves told the Star Tribune that he will not seek office again for the forseeable future, although he won't rule it out.

"Never say never, but I'm a businessman not a politician," he said.
