Mitt's Michigan Muscle

CBS reports:

According to a new Rasmussen Poll, Romney has a six-point lead over Santorum in Michigan, 40-34 percent. That’s a complete reversal from a similar poll taken three days ago that showed Santorum withi a four-point lead. 

Another poll from Mitchell Research showed Romney had a three point lead in Michigan, which was significantly different from the nine point lead Santorum enjoyed just last week from the same polling operation.

AP reports from Muskegon, Michigan:

The standing-room-only crowd crammed into a Holiday Inn conference room in this industrial city roared with approval as Rick Santorum served up applause lines on why Michigan Republicans should choose him, not native-son Mitt Romney, as the GOP presidential nominee. Santorum's message, heavy on religious values and contempt for bailouts, was perfect for an audience in this stronghold of social conservatism and tea party sentiment.
But Santorum's campaign couldn't fully capitalize on the moment, revealing a shortcoming that Romney hopes will help him win Tuesday's primary despite the surging enthusiasm and favorable poll numbers for his chief opponent.
Santorum's campaign organization is so sparse in Michigan that no one was available to collect the names and email addresses of the people streaming out of the hall after the speech, a practice that's a staple of political organizing and get-out-the-vote efforts. By contrast, Romney has a deep and experienced organization working in every corner of the state. Seven of Michigan's nine Republican congressmen have tapped their campaign networks to help Romney put out calls, set up events and harvest donors.
"Mitt has a great advantage as far as having boots on the ground," said Jim Thienel, GOP chairman in Oakland County, an affluent area where virtually the entire Republican party apparatus is part of the Romney campaign
