Where in the World are the Candidates on Tuesday?
But tomorrow night will be first time when the four candidates will be in four different states when the votes are tallied.
Not surprisingly, their choices signal where they think they may be the most successful. Romney will be in Colorado, where the Mormon population may help boost his numbers. Santorum will be in Missouri, where Republicans tend to be socially conservative. Paul will be in Minnesota, which boasts a strong tea party streak.
Perhaps in a sign that he doesn't think he'll win in any of the three states voting tomorrow, Gingrich plans to be in Ohio on the first day of early voting. Romney pounded Gingrich among early voters in Florida, and Gingrich's trip to Ohio indicates he doesn't want that to happen again.
