The 2010 Minnesota gubernatorial election was held on Tuesday, November 2, 2010, to elect the 40th governor of the U.S. state of Minnesota for a four-year term to begin in January 2011. The general election was contested by the major party candidates State Representative Tom Emmer (R–Delano), former U.S. Senator Mark Dayton (DFL), and Independence Party candidate Tom Horner. After a very close race, Dayton was elected governor. Emmer would be elected to the United States House of Representatives four years later.

This was the first time the Democrats won the governorship since Rudy Perpich won re-election in 1986. With a margin of 0.4% (or 8,770 votes), this election was the closest race of the 2010 gubernatorial election cycle.

Republican primary After incumbent Governor Tim Pawlenty announced in June 2009 that he would not seek a third term, the field was open for Republicans to seek their party's endorsement. At the Minnesota GOP's off-year state convention in October 2009, former Representative Marty Seifert took first place in a straw poll with 37% of the vote. Representative Tom Emmer took second place with 23%, Patricia Anderson had 14%, and the rest of the participating candidates received less than 10% each.

Seifert had another victory in the February 2 precinct caucuses, winning a statewide straw poll of caucus attendees with 50% of the vote, followed by Emmer with 39%. None of the other candidates got beyond single digits. Delegates to the state convention, however, were more closely divided between Emmer and Seifert than the initial straw poll indicated. Both camps claimed a delegate lead throughout the process leading up to the state convention, but the outcome was uncertain and was ultimately decided on the convention floor.

On April 30, Emmer won the Republican endorsement at the party's state convention in Minneapolis. After Emmer won 56% of the vote on the second ballot, Seifert withdrew from the race and threw his support to Emmer. Emmer then chose Metropolitan Council member Annette Meeks as his running mate for lieutenant governor.

Emmer won the August 10 primary, earning a spot on the November ballot.

Results

Democratic–Farmer–Labor primary The list of candidates seeking the DFL's nomination was long going into the February 2 caucuses, with over 11 candidates having submitted their names for the candidate preference ballot. Former U.S. Senator Mark Dayton notably declined to be included on the ballot. Minneapolis Mayor R. T. Rybak won the straw poll with 21.8% of the vote, with State House Speaker Margaret Anderson Kelliher receiving 20.1%, and "uncommitted" receiving 14.7%. The other each candidates received single-digit support.

Former State Senator Steve Kelley dropped out of the race after a disappointing result in the straw poll. State Senator Tom Bakk also dropped out on March 20 after announcing at the St. Louis County Convention that he believed his chances of winning were slim.

On April 24, the DFL State Convention was held in Duluth. State Senator John Marty withdrew from the race after seeing lower than expected support on the first ballot, and State Representative Tom Rukavina withdrew after the fourth ballot, endorsing Kelliher. State Representative Paul Thissen withdrew after the fifth ballot, and before the results of the sixth ballot were announced, Rybak withdrew as well, endorsing Kelliher. Kelliher was subsequently endorsed by the convention. Ramsey County Attorney Susan Gaertner, who had not sought the DFL endorsement but was planning to run in the primary, dropped out two days later. That left Kelliher facing Dayton and former State House Minority Leader Matt Entenza in the August primary.

Shortly after the end of the 2010 legislative term, all three major DFL candidates had announced their choices for lieutenant governor. On May 21, Kelliher announced that John Gunyou would be her running mate. Gunyou was Minnetonka City Manager and was state finance commissioner in Republican Governor Arne Carlson's administration. On May 24, Dayton announced Yvonne Prettner Solon as his running mate. Solon was a psychologist and three-term state senator. On May 27, Entenza announced Robyne Robinson as his running mate. Robinson was a small-business owner and former TV anchor.

Dayton narrowly won the August 10 primary, earning the right to serve as his party's nominee. He was formally endorsed by the DFL on August 21.

Results

General election Early polls showed Emmer even with his likely DFL opponents, with Horner trailing far behind, and a large percentage of voters undecided. As the race progressed, polls showed the candidates even, or Dayton with a small but significant lead. The nonpartisan Cook Political Report, CQ Politics and pollster Rasmussen Reports rated the gubernatorial election a tossup, while New York Times political statistician Nate Silver gave Dayton an 86% chance of winning and Emmer 14%.

Dayton led Emmer at the close of balloting by 8,770 votes (0.42%). The margin of victory was small enough to trigger an automatic recount under state law, but analysts generally thought it unlikely that Dayton's lead would be overturned.

Dayton became just the fourth victorious Minnesota Democrat to win a gubernatorial election with a Democrat in the White House in 28 cycles.
