Once Biden started working with Romney none of that would matter anymore, I think he would.
I would like to think you're right. I would like to think Biden would continue to be a team player even though he was drafted onto a different team. And again, I'm probably one of the few conservatives who does like Biden. But it does present some interesting dynamics:
The left has typically demonized both the GOP President and Vice President. And they love using cherry picked statements to do it. Would they do that to Biden, one of their own, if Biden chose to be a loyal vice president to Romney? I mean there are hundreds of clips out there of Biden demonizing Romney, Romney's words, Romney's plans/policies/proposals. If he had to do a 180 switch, how would that look? Would the GOP praise it or would they hold Biden in contempt? Would the Democrats accept it or hold Biden in contempt?
And if Biden stayed true to his stated convictions for the last four years, how badly would that handicap Romney in not having a vice president he could trust and depend on?
