Did my trollish subject get you here?
I'm wondering if any Ron Paul supporters are going to be setting up any Bitcoin related Ron Paul services, such as a central place where Bitcoins could be converted to dollars (and the total reported, showing how many Bitcoins people are willing to give to help his campaign) which are donated to the Ron Paul campaign. Or a place that sells Ron Paul stuff, like shirts, buttons, and blimps. It's kind of late to be thinking about, but he has a big money bomb the 5th for the first debates.
I think it's probably too difficult to legally do this for donations. Too many requirements in knowing who is sending the money and such.
But selling campaign material probably is kosher, as long as you don't do any trademark infringements or something.
Someone with more official capacity could put Bitcoin for donations, and sell them immediately and gather the same personal info required of anyone donating cash. There are cash limits no how much any person can contribute, so the value would have to be calculated right away.
I should also add that supporting Gary Johnson is also going to be a good thing if you like Ron Paul. I'd love to see both of them on the stage together so that it won't be as easy to say they are kooks when they aren't alone.
I'll talk to my friend who's wife works for RP to see if they are interested at all if you want. It might not be big enough to be worth the effort, though. To set it up, they may have to spend a lot of money, which is more than they'd bring in, so the funds would be better spent doing other things.
