In presidential elections, Montana was long classified as a swing state, though the state has voted for the Republican candidate in all but two elections from 1952 to the present. The state last supported a Democrat for president in 1992, when Bill Clinton won a plurality victory. Overall, since 1889 the state has voted for Democratic governors 60 percent of the time and Democratic presidents 40 percent of the time, with these numbers being 40/60 for Republican candidates. In the 2008 presidential election, Montana was considered a swing state and was ultimately won by Republican John McCain, albeit by a narrow margin of two percent.
