PPP: Santorum beating Romney in Michigan

[True Federalist (진정한 연방 주의자)]

Mittens is no Rick Lazio. Paladino won because NY Republicans didn't want to nominate some washed-out down-stater whose last major accomplishment was losing to Hillary Clinton. Paladino could not gave won the primary without unusually high enthusiasm upstate + low enthusiasm downstate. Santorum can't take advantage of the regional divide in the same way.

Why not?  I've seen no evidence that anyone other than Politico is all that enthused about Romney.
