Liberal, with No Apologies - Walter Mondale

A one-term Vice President known for being liberal on issues and associated with Hubert Humphrey, Carter's Vice President Walter Mondale changed the office more than anyone else. He moved it from the Senate to the White House, where it has been since. He also ran for President twice, and ended up with a 49-state blowout.  Yet, he never doubted what he did was right.
