The 2012 United States presidential election in Missouri took place on November 6, 2012, as part of the 2012 general election, in which all 50 states plus the District of Columbia participated. Missouri voters chose 10 electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan. Missouri was won by Mitt Romney, who took 53.76% of the vote to Barack Obama's 44.38%, a margin of 9.38%. Although a battleground in past elections, Missouri is considered to be trending toward the Republicans, having been the only swing state to be won (albeit narrowly) by Republican John McCain in the 2008 election. Consequently, the state was not heavily contested by either side in 2012, and the Republicans ultimately carried Missouri by the largest margin since 1984. Also, this was the first time since 1900 that Missouri was not carried by the victor of the presidential contest two times consecutively (after Obama had failed to win the state in 2008), as well as the first time since 1900 when the overall loser of the presidential election won the state by a margin larger than 1% of the statewide vote. Obama carried only three counties and the City of St. Louis. He carried Boone County, home to Columbia and the University of Missouri; Jackson County, which is where most of Kansas City is located; and St. Louis County.
