This is definitely logical, except I really don't foresee Massachusetts going Republican any time soon, even with Scott Brown as the candidate. However, Rhode Island could possibly go Republican instead. The problem is that these are all hypotheticals. Furthermore, wouldn't Brown end up losing traction in the Deep South as a result?
My guess is that his margin of victory in the Deep South is smaller, but still strong enough to win. It's possible that after that landslide, the GOP shifts to a strategy to defend Midwest and Mid-Atlantic states like PA, VA, MI, WI, MN, OH, etc.
