"The constitutionally mandated mechanism for selecting the president of the United States. A total of 538 votes exist in the Electoral College and are distributed among the American states based on the combined number of senators and representatives each state has in the U.S. Congress. In addition, the District of Columbia possesses three electoral votes. Each state selects the predetermined number of electors from its population—members of Congress and other federal officers are ineligible for selection—and has the body meet approximately one month after the American electorate votes in the general election. The outcome of the general election governs the votes of the members of the Electoral College, as all states but two (Maine and Nebraska) cast their votes in a winner-take-all fashion based on the winner of the general election in each state."
