The 2008 United States presidential election in Arizona took place on November 4, 2008, and was part of the 2008 United States presidential election. Voters chose 10 representatives, or electors to the Electoral College, who voted for president and vice president.
Arizona was won by Republican nominee and native son John McCain with an 8.48% margin of victory over Democrat Barack Obama. McCain had served as United States Senator from the state since 1987, and enjoyed high approval ratings. Prior to the election, sixteen of seventeen news organizations considered this a state McCain would win, or a red state. Some polls taken near Election Day in 2008 showed Democrat Barack Obama closer than expected to winning it, but these did not come to fruition, as McCain won Arizona by high-single digits and carried all but four of the state's 15 counties. Nonetheless, this was closer than any of McCain's Senate victories and was a smaller margin than Bush's 10.5% margin 4 years earlier.
Obama became the first Democrat to win the White House without winning Gila, Greenlee, La Paz, or Pinal Counties since Arizona statehood in 1912, as well as the first to do so without winning Navajo County since Lyndon B. Johnson in 1964.
Arizona was one of only two states that voted against Obama in both 2008 and 2012 that his vice president Joe Biden would go on to win in 2020, the other being Georgia.
