Zero tried to condescend to Mitt but ended making himself look petty and vindictive... like the rest of liberal-dom.
Exactly right. He tried to put Mitt in his place. How many votes does he think he won with that (even if he had been right)? Anybody who liked that putdown is already in the tank for Obama (and out of their mind).
He lost voters because he came off looking like a snarky, irresponsible, little smartass -- which is accurate.
