After the 2000 U.S. presidential election, just about everybody in the United States was talking about the Electoral College. In the end, of course, Gore won the popular vote (more Americans voted for him), but Bush actually won the presidency, because he was awarded the majority of the votes in the Electoral College.

In this edition of How Stuff Works, we'll explain how this interesting system works. How is it that a candidate could win more votes overall and yet not be elected? What would happen if there were a tie in the Electoral College? Who then would elect the president? You will find out about the past elections that weren't decided on Election Day but weeks later, when the Electoral College met, and some that weren't decided until months later. You'll also learn about the strange election of the first son of a former president to win the presidency.
