Albert Arnold Gore Jr. is an American politician and environmentalist who served as the 45th vice president of the United States from 1993 to 2001 under president Bill Clinton. Gore was the Democratic nominee for the 2000 presidential election, losing to George W. Bush in a very close race after a Florida recount.
Gore was an elected official for 24 years. He was a representative from Tennessee and from 1985 to 1993 served as a 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. The 2000 presidential election was one of the closest presidential races in history. Gore and his running mate Joe Lieberman won the popular vote, but after a controversial election dispute over a Florida recount, he lost the election to Republican opponent George W. Bush in the Electoral College.
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 the Nobel Peace Prize in 2007.
