(AP) BISMARCK, N.D. - Democratic candidate Heidi Heitkamp has won the U.S. Senate race in North Dakota, defeating Republican Rep. Rick Berg.
Heitkamp won the race by fewer than 3,000 votes, and Berg could have asked for a recount.
He conceded the race Wednesday with a qualifier: He was stepping aside barring any unforeseen circumstances with the state canvasing board that certifies the race results.
That canvasing process is to begin Friday. It will account for late-arriving absentee ballots that were postmarked in time to be counted in the election.
Berg had been expected to win the race, and Republicans had counted on his victory in their failed attempt to take control of the Senate.
