In the eighties, I often found myself amazed at how many of my fellow musicians were very left-leaning. Not all, certainly, but a lot were. Go figure. With regard to Mrs. Bachmann, there are conservative musicians out there. The first that comes to mind would be Vince Furnier - Alice Cooper. He’s a registered Republican, last I heard. There are others, too. Just as Jon Voight isn’t the only good guy in Hollywood, there are musical folks out there. A better idea, though, might be for her to find a few musicians and just write her own theme song. Then there aren’t any rights issues. Yes, it’s more difficult, but at least it avoids this sort of silliness. Just a thought. ;)
Slayer and metallica are right wing.
Found this list of conservative musicians:
