The 2010 New Mexico gubernatorial election took place on November 2, 2010. Democratic governor Bill Richardson was term limited and could not seek a third consecutive term. On June 1, 2010, the Republicans nominated Susana Martínez, the district attorney for Doña Ana County, New Mexico, and the Democrats nominated Lieutenant Governor Diane Denish. While it was initially thought that Richardson would resign early to become Secretary of Commerce in the Obama administration, Richardson withdrew from the position due to allegations of corruption that were later cleared and he remained governor until the conclusion of his term. Susana Martínez won the election on November 2, 2010, and became New Mexico's first elected female governor, as well as the first Latina governor of any state.
