Have many people tried emailing bands for endorsements?
Radiohead will be the big one, and they're not afraid to speak up about the views they stand for. Thom Yorke even refused meeting the Prime Minister of the UK because he didn't agree with his policies. And he CERTAINLY doesn't agree with the war.
However, energy may be a bit of a shitty issue to sell to them.
I'll try and stir up a bit of discussion on the Radiohead forums and give them an email. I'll do the same for Muse aswell.
If you know any local bands, email them! People who listen to rock are very likely to stand up for freedom! If we can get as many musicians as possible on board, the word will spread like wildfire and we'll be a very formidable force.
Also, the music scene is influenced a lot by fashion. If we can make it 'cool' for bands and fans to support Ron Paul, then not only will have we have the doctors and economists on our side, but also the musicians. Such a diverse mix will be difficult to overcome.
