U.S. Representative District 1 – Tim Walz holds on
Tim Walz, the DFL incumbent, held on in a very tight race. Walz was neck-and-neck with challenger Jim Hagedorn throughout the night.

U.S. Representative District 2* – Jason Lewis wins

Independent candidate Paula Overby got 7.79 percent (28,508 votes).
Lewis will replace Republican Rep. John Kline, who decided not to run for re-election after holding the seat since 2003.

U.S. Representative District 7 – Peterson re-elected

U.S. Representative District 8* – Nolan ekes by
Arguably the big one of the night, with the second highest national spending on this race, DFL incumbent Rick Nolan edged out Stewart Mills to hold on to his seat.
Constitutional amendment – approved
The ballot question asked if lawmakers' power to set their own pay should be removed. With 61 percent of precincts reporting at of 11 p.m. Tuesday, an estimated 75.78 percent of votes were yes votes.
For a constitutional amendment to pass, 50 percent plus one of all ballots must be yes votes. This percentage means it's likely that the amendment will pass.
Supreme Court – Hudson is the likely winner
Incumbent Natalie Hudson, who was recently nominated to the Minnesota Supreme Court by Gov. Mark Dayton, looks as if she'll win the race against challenger Michelle MacDonald. As of 12:43 a.m. Wednesday, Hudson had 58.97 percent of the vote.
*These races were the most competitive in the state – and country – heading into Election Day.
