The legendary rocker says that while he doesn't support her positions, he is impressed by the mark she's made on the country since the 2008 election.
Mellencamp says people get the wrong idea about her intellect "just because she says things and winks."
He says she "knows exactly what's she doing" and "she wouldn't be where she is today if she didn't."
Mellencamp gives Palin credit for handling the rough world of politics. He says "she's pushing the right buttons" and "you can't be stupid and do that."
The 59-year-old rocker is no stranger to the political arena. He supported Barack Obama's campaign in 2008 and asked Palin's running mate, John McCain, to stop using his songs at rallies.
