The final Senate race of the election is now officially over. In North Dakota Republican Rick Berg has conceded the race to Democrat Heidi Heitkamp. With 100 percent of precincts reporting Heitkamp ended up with roughly a 3,000 vote lead over Berg.
The seat opened when Democrat Kent Conrad decided not to run for re-election. Since North Dakota went overwhelmingly for Mitt Romney, it was widely assumed that this would be a big pick up opportunity for Republicans, but Heitkamp turned out to be a supreme campaigner.
This is a huge upset victory for Democrats. Basically all the final polling of the state had Berg leading by decent margin.
The final result is that Democrats picked up two seats in the Senate. The Democratic caucus will now have 55 members, assuming that Independent Angus King of Maine decides to caucus with them.
