Sure the Dems would love a RINO running as the Republican Candidate.
Look at his lame duck voting record.
About 5 Pubbie RINOs on my table need to be removed....
I would love to see him run, something to split the Democrat vote with Romney in the Republican primaries. The problem is that he could be a factor in the first one but would diminish rapidly after that. We need serious competition for Romney in order to neutralize the Democrats.
