This is not a self-selected poll. It’s an automated random telephone poll.
I think what this shows is that there are a lot of people who don’t know much about Paul, but have vaguely positive feelings about him, in part because they perceive him to be outside the establishment.

Maybe it’s an ABO poll, anybody but Obamadinejad.
