Everyone expects this campaign to go negative early on both sides. (Recalling a Paul Conrad political cartoon in the 62 Nixon v Brown CA gov. race- one side carrying sign vote against Nixon , the other side vote against Brown) For all the cliched use of flip flopper, an objective moderate cannot look at Romney as ask what, actually, would I get if this guy was elected. I have no idea, and neither does anyone else.
I think that's the deal breaker.
