Albert Arnold "Al" Gore, Jr. (born March 31, 1948) is a former American politician. He was the 45th vice president of the United States under Bill Clinton from 1993 to 2001. Before that, he was a U.S. senator and a congressman for Tennessee. He is a Democrat.
He was chosen as the Democratic nominee of the 2000 United States presidential election, but lost the electoral vote to Republican candidate George W. Bush because of Florida and the US Supreme Court ruling a 5-4 favor of Bush. He was supposed to be president before the supreme court decision. Gore got more votes, though.
After the election, Gore became an activist focusing on climate change. Gore won the Nobel Peace Prize in 2007.
