LOL... This has been talked about at length here with detailed explanations. You really don't get how Paul attracts independents and even dems or liberal leaning voters?
I don't read every thread, or every post in every thread, so no, I don't recall reading "detailed explanations" about how Ron Paul attracts independents and Democrats. I find it hard to believe. In fact, most of the liberals I know who have talked about Ron Paul do not like him. I posted an article I got from one of those liberal friends a little while back: http://www.getbig.com/boards/index.php?topic=401296.0
Ron Paul's support outside of the Republican party is primarily with libertarians, 911 CT nuts, and kids, none of whom make up a significant voting block and/or influence national elections. And his support within the Republican party is fairly limited.
He will do well in Iowa and NH, in part because he has spent so much time and money there and Romney has basically conceded Iowa, but outside of that he isn't going to win a single primary IMO.
