21 Mellencamp for Obama

Hillary Clinton hammered Barack Obama for his "bitter" remarks as "elitist" and "out of touch" with small-town voters. She even played John Mellencamp's "Small Town" at an event in Indiana earlier this month.

But the singer himself is performing for ... Obama. Mellencamp is on the billing for an Obama appearance on Tuesday night in Evansville, Indiana, at Roberts Municipal Stadium, where the campaign hopes to be celebrating a better-than-expected performance in the Pennsylvania primary. It's probably not a good sign, however, that he won't be in Pennsylvania that night.

Clinton will be at the Park Hyatt in Philadelphia, where it is doubtful that she will be playing "Small Town" or "Streets of Philadelphia," for that matter. The latter is a Bruce Springsteen song, and he has endorsed Obama.

Here's Mellencamp in November, appearing in Iowa with the candidate he had previously endorsed, John Edwards.
