The 2000 United States Senate election in Florida was held on November 7, 2000, on the same date as the U.S. House of Representatives and presidential election. Incumbent Republican Senator Connie Mack III decided to retire instead of seeking a third term. Democrat Bill Nelson won the open seat, even as Republican presidential nominee George W. Bush narrowly triumphed over Al Gore in the state by a mere 537 votes. Bill McCollum's 46.19% popular vote percentage is the highest for a losing Republican United States Senate candidate in Florida.
