Who Are the "Other 3 Dudes" Running For the Democratic Nomination?

Age: 62
Credentials: Former Republican senator and independent governor from Rhode Island. Cochaired the group Independents and Republicans For Obama in 2008.
Fun fact: Chafee was encouraged to leave the Republican Party by none other than fellow Democratic candidate Martin O’Malley. Talk about a backfire, O’Malley. Chafee also spent the better part of his 20s working in racetracks putting shoes on horses, so . . . we guess he knows about hard work?
How he fared in debate no. 1: In his opening statements, Chafee noted that he never had any scandals — something rare for a long-term politician. It’s also a handy way to differentiate himself from Hillary Clinton.
