The 2008 United States presidential election in Maine took place on November 4, 2008, and was part of the 2008 United States presidential election. Maine is one of two states in the U.S. that instead of all of the state's four electors of the Electoral College to vote based upon the statewide results of the voters, two of the individual electors vote based on their congressional district because Maine has two congressional districts. The other two electors vote based upon the statewide results. See below in the section of Electors for more information.
