By your and my standards - yes. By masshole standards he's conservative.
I voted for Scott Brown last time.
Elizabeth Warren is worse than Scott Brown.
But Scott Brown has shown himself to be undeserving of my vote. He'll have to get elected without my vote in November, because I don't vote for leftists, and I don't vote for the lesser of two evils. I oppose evil, I don't support it.
Same goes for Mitt.
