The Michigan primary comes days before the one in South Carolina on Saturday. McCain is not scheduled to be in Michigan on primary night. He'll decamp to Charleston, S.C., in the afternoon.
Former Tennessee senator Fred Thompson, another candidate, is concentrating South Carolina.
Former New York City mayor Rudy Giuliani is banking on the Florida primary Jan. 29. On Fox News Sunday, Giuliani downplayed his poll numbers and the fact that some campaign staff members are forgoing paychecks for a month. "It's a wide-open race," Giuliani said, and "we've got a good long campaign here in Florida. … We've got a lot of time until Jan. 29."
In Michigan, a big question in the Republican primary may be the size of the Democratic turnout. Anuzis said 17% of the vote in the Republican primary in 2000 consisted of crossover Democrats.
The national Democratic Party stripped Michigan of its delegates to the national convention because the state party moved up its primary date. The major Democratic candidates have not campaigned in the state. Hillary Rodham Clinton is on the ballot, but Barack Obama and John Edwards are not.
Michigan Republicans face the same situation, but those candidates are contesting the primary.
Michigan-based independent pollster Ed Sarpolus said McCain can win if he gets enough Democrats to cross over, as he did eight years ago. The momentum from New Hampshire certainly gives him a chance.
"Romney's had money, time and organization. … He's got older voters who remember his dad," Sarpolus said. "The only reason McCain's in play is because of New Hampshire."
