What are your thoughts on Dennis Kucinich?

I am quite left-wing myself but I find him unreliable. As mayor of Cleveland he left the city bankrupt and during his tenure showed no interest in the environment or any of the issues he now proclaims is the champion. He used to be anti-abortion and very Catholic, now he is pro-choice and a feminist? I don't understand how you can flip-flop on such important issues. He claims to be looking out for the little man, I personally think the only little man he cares about is Kucinich himself.
