He said it was treason against rock and roll, not against the U.S., hippie.
And what I loved about the article was when he said "If you're listening to a rock star in order to get your information on who to vote for, you're a bigger moron than they are. Why are we rock stars? Because we're morons. We sleep all day, we play music at night and very rarely do we sit around reading the Washington Journal."
I don't quite agree with him 100 percent, because I think political activism has its place in the music world, but I just think the quote is funny.
And I highly doubt that Dre is a Republican since I seem to remember that Outkast was supporting Wesley Clarke during the Democrat primaries; however, you never know -- look at the Ramones for example...
