I don't think they can, because they have put all their hopes and faith (so to speak) into Harry Reid. For them to try that with Mitt would be seen as very hypocritical.
On the other hand, what they WILL do is continue to pit Conservative circles against him in the Primary. That’s their only hope.
Huh? When has hypocrisy ever stopped the media? You know they will ask questions like...”Can the South really vote for a non-christian over a black Christian? If so it proves they are racists.”
