Why is Obama postponing a trip to Columbus, Ohio to come to Madison, Wisconsin the day after the first debate?

Larry Sabato, of the University of Virginia Center for Politics, says: "Obama naturally would want to be on friendly turf after the debate, and he may think he'll draw a bigger turnout here than in Columbus... Columbus is mixed politically... Madison is heavily Democratic." And: "He may want to declare victory in the debate right there in Ryan's backyard."

Ben Sparks, spokesman for the Romney campaign in Wisconsin says: "He's finally acknowledging he has a Wisconsin problem."

Charles Franklin, director of political polling at Marquette University, flips that analysis around: Maybe Obama thinks he doesn't have an Ohio problem.
