how is the number of votes in the electoral college determined?
When U.S. citizens vote for President and Vice President every election year, ballots show the names of the Presidential and Vice Presidential candidates, although they are actually electing a slate of electors that represent them in each state. The electors from every state combine to form the Electoral College. Each state is given a set number of Electors, determined by the number of the its U.S. Congressmen. The number of Representatives in each state correlates with the state population and is amended every decade when the Census is taken. The number of Senators is always two.
