Following up on my post this morning regarding whether conservatives and libertarians would stay home or support Obama if Newt were the Republican nominee, I wonder which if any of the other candidates generates such feelings.

So, here is the Doomsday Poll, in two parts.  First, which of the candidates, if nominated, definitely/likely would cause you to stay home or vote for Obama.  Second, which of the candidates, if nominated, possibly would cause you to stay home or vote for Obama.

The polls will be open until noon (Eastern) on Wednesday.
