The 2010 Nevada gubernatorial election was held on Tuesday, November 2, 2010, to elect the governor of Nevada, who would serve a four-year term to begin on January 3, 2011. Despite speculation that incumbent Republican governor Jim Gibbons would not run for a second term due to low approval ratings, he ran for re-election. He struggled in the polls, and ultimately federal judge and former attorney general of Nevada Brian Sandoval secured the nomination. Sandoval defeated Democrat Rory Reid, son of then-current U.S. Senate Majority Leader Harry Reid, who won his fifth term in the Senate on the same ballot.
