Pics: How America elects its president ?

During the election, Americans from each of the 50 states and the District of Columbia head to the polls to cast their vote for President. But the tally of those votes -- the popular vote -- does not determine the winner. Instead, presidential elections use the Electoral College -- a process by which the President and the Vice President is chosen by "electors". To win the election, a candidate must receive a majority of electoral votes.
