We could possibly get an endorsement from Greg Puciato, singer of the Dillinger Escape Plan. They're not a HUUUUGE band, but they're very big and play big festivals, have performed on Conan and tour with a lot of well known bands (opening up for Soundgarden next month). I think he's leaning towards anarcho-capitalism and every time he posts a blog, it gets mentioned on pretty much every major metal site, so maybe that's something worth looking into?
Annnnd Alec Baldwin? At the very least he said Ron could beat Obama, that's a step in the right direction?
