President Bill Clinton

President Bill Clinton won the role of American POTUS in 1992 in a rare three-way final.
Clinton, known as "Slick Willie" to his fellow actors, was only a middling, unassuming POTUS until a homemade porn tape starring Clinton surfaced on The Internet, after which Clinton became the most popular President ever.
Clinton's son, George W. Clinton, was expected to be a major contestant on Campaign! in 2008.
