Lincoln Chafee hopes to score 'Triple Crown' of politics

As he launches his 2016 presidential campaign on Wednesday outside Washington D.C., former Rhode Island Gov. Lincoln Chafee will take a key step toward attempting to achieve the triple crown of politics.

The 62-year-old has won major offices as a Republican (as a U.S. senator) and Independent (as a governor) already and if successful in his bid for the White House, would add Democrat to that list.

A outsider win might seem like a challenge going up against Hillary Clinton, but he has potential.

Chafee has both executive and legislative experience under his belt. He has also hinted at making Clinton's vote for the Iraq war in 2002 — something she's called a mistake — a focus of his campaign.

However, voters will need to actually know who he is if he wants to get the keys to 1600 Pennsylvania Ave.

CNN points out that Chafee hasn't been included in an large majority of public polling of the Democratic primary, something he says he's well aware of.
