On July 9, 1992, Bill Clinton chose Al Gore to be his running mate. They won the 1992 election, and Gore was inaugurated as the 45th Vice President of the United States on January 20, 1993. They were re-elected in 1996 to their second term in office.
The American economy expanded greatly during their administration. The main contributor to this was the Omnibus Budget Reconciliation Act of 1993, for which Gore was the tie-breaking vote. Their administration worked tirelessly to slow federal spending and balance the federal budget.
The Clinton/Gore administration was around until January 20, 2001. They were replaces by the Bush/Cheny administration. However, Al Gore decided to give them a run for their money during the 2000 election.
After two terms as Vice President, Gore ran for President of the United States. In August, he surprised many people when he announced that his running mate would be Joe Lieberman. 
At first, it appeared that Al Gore would be the winner in this election, but there was a turn in events when the Florida ballots appeared to be needing a recount. The case was brought before the Supreme Court of the United States.
However, in the Bush V. Gore case, the ruling was 5-4 in favor for the fact that the Florida recount was unconstitutional and that no constitutionally valid recount could be completed. It was this decision that tipped the scales and put Bush into office.
