Heh, I thought it was probably the implication that Paul was a career politician although he is primarily a gynecologist. He continues to deliver babies when he's in Texas and he has spent a few terms out of office (practicing medicine) since he was first elected in the 70s. Maybe that's a self-interested assumption that exposes my own leanings, though.
Probably people reading an endorsement of Ron Paul in your post, though none is really there.
