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 easily won Arizona and carried all but four of the state's 15 counties.[1] Nonetheless, this was closer than any of McCain's Senate campaigns.
