The United States is one of few contemporary democracies that does not choose its chief executive officer through direct popular vote. Rather, the President of the United States is formally chosen by the Electoral College, and a majority of votes in the Electoral College is required to secure election to the Presidency. In 2000, Republican George W. Bush won a 271–266 majority in the Electoral College despite the fact that his opponent, Al Gore, won about half a million more popular votes. The Electoral College system can be conceptualized as a mechanism by which the results of separate elections in each state and, since 1964, the District of Columbia, can be aggregated to produce a nationwide outcome. It has not experienced major reform since 1804, despite the fact that many critics have regarded the system as archaic, outmoded, and essentially undemocratic. Since the early nineteenth century, more than 600 proposed constitutional amendments concerning the Electoral College system have been proposed and debated in Congress. Some would eliminate the Electoral College system altogether and replace it with direct popular vote. Others would retain the Electoral College system but change the way electors are selected or affect the relationships between popular and electoral votes in each state. Because the popular vote in Florida was very close, and because the remaining states were so closely divided, Florida proved to be the pivotal state in the 2000 presidential election. The closeness and controversy surrounding the Florida outcome has renewed efforts on the part of critics to eliminate or reform the system. However, analysis of the 2000 campaign underscores the fact that both sides based decisions concerning their campaign strategies and allocations of human financial resources in an effort to win an electoral college majority, within the constraints of the present system. It is unlikely that there will be sufficient support to overturn or reform the system through constitutional agreement in the foreseeable future.
