32. John Nance Garner
President: Franklin Delano Roosevelt, 1933-1941
Dubbed "Cactus Jack" by the press, John Nance Garner once described the role of the vice president as being "not worth a bucket of warm piss." When FDR decided to run for an unprecedented third term, Garner campaigned against him, hoping to get the job of president himself. He failed, making him the first VP to date to run against a sitting president. Not surprisingly, he was dropped from the ticket.
