Although he's still technically in the exploratory stage of a presidential run, former Rhode Island Senator and Governor Lincoln Chafee has for all intents and purposes declared he's making a bid for the White House in an interview with CNN.
Chafee, of course, stands no chance in hell of winning the Democratic Party nomination and he knows it. He's been a Democrat for less than three years and most Democrats outside of Rhode Island probably still think of him as a Republican albeit a very liberal one.
But Chafee has made it clear why he is running: The Iraq War:
That was a moment where the premise for going to Iraq was so false that there were weapons of mass destruction; she didn't do her homework. We live with the ramifications. You may say that's 12 years ago — that's a big motivator for me running. If you show a lack of judgment, lack of doing homework then, what can we expect in the future?"
