Al Gore, a Senator from Tennessee, also chose to run for the nomination. Turning 40 in 1988, he would have been the youngest man to contest the presidency on a major party ticket since William Jennings Bryan in 1896, and the youngest president ever if elected, younger than John F. Kennedy at election age and Theodore Roosevelt at age of assumption of office. He eventually became the 45th Vice President of the United States under Bill Clinton, then the Democratic presidential nominee in 2000, losing to George W. Bush, George H.W.'s son.
