Gore was the Democratic nominee for president of the United States in the 2000 presidential election, which he lost to George W. Bush.The son of politician Albert Gore Sr., Gore was an elected official for 24 years. He was a U.S. representative from Tennessee (1977–1985) and from 1985 to 1993 served as a U.S. senator from that state. He served as vice president during the Clinton administration from 1993 to 2001, defeating incumbents George H. W. Bush and Dan Quayle in 1992, and Bob Dole and Jack Kemp in 1996. As of 2023, Gore's 1990 re-election remains the last time Democrats won a Senate election in Tennessee. Gore was the Democratic nominee for president of the United States in the 2000 presidential election - in which he lost the electoral college vote 266–271 to Republican nominee George W. Bush, despite winning the popular vote by approximately 543,895 votes. The election concluded after the Supreme Court of the United States ruled 5–4 in Bush v. Gore against a previous ruling by the Supreme Court of Florida on a re-count that would have likely given Gore a razor-thin lead in the state of Florida, had the re-count continued as planned. He is one of five presidential candidates in American history to lose a presidential election despite winning the popular vote. After his term as vice-president ended in 2001, Gore remained prominent as an author and environmental activist, whose work in climate change activism earned him (jointly with the IPCC) the Nobel Peace Prize in 2007.
