If Ron Paul actually supports SOPA, but he says he opposes it, there's no source that's going to tell you about that, at least until it actually comes up for a vote. So if you don't take his word for it, you're stuck looking at his past voting record on other bills. That's public record, and you can find it pretty easily all over the place.
