Tomorrow's the big day for the GOP race. It could be the end of Romney's campaign or his restoration to extremely weak front runner status.
Nate Silver projects:
Mitt Romney 38.8% of the vote 64% chance of winning
Rick Santorum 36.7% of the vote 36% chance of winning
Ron Paul 13.2% of the vote 0% chance of winning
However, recent polling may indicate Santorum picking up momentum with recent polls showing him closing the gap with Romney and a recent PPP poll showing: "encouraging things for Santorum."
Santorum could also be assisted by the following:
"Michigan's primary rules allow Dems to vote in the state's GOP primaries. The liberal site DailyKos and other progressive partners have been trying to drum up enthusiasm for 'Operation Hilarity' -- an effort to get Democrats to vote in the GOP primary and tilt the vote against Mitt Romney. The Santorum campaign evidently decided they'd take votes from any legitimate source."
From a Democrat's point of view, it's a mistake to mess Romney up any more, as I have previously argued. Continuing to weaken him could draw in a credible Republican candidate. Logically, if I were a Michigan Democrat I'd have to lean towards voting for Romney.
