So, if it comes down to Mitt and Newt after Saturday, the campaign is going to get dirtier and dirtier. Mitt will probably win because Newt runs his mouth more than Biden, and has skeletons in his closet on top of that. People don't trust him. But, if Mitt thinks that the two-thirds to three-quarters of Republicans who didn't vote for him so far or don't show for him in the polls, will rally round him in the general election, he should think again. Real hard-core conservatives hate him. I'd bet Bachmann or another will run a third party campaign. If that happens, Obama won't have to leave the White House to be re-elected. He's the most vulnerable incumbent since Carter, but unlike Carter, he has no strong opposition candidate.
