I do not doubt Ron Paul's sincerety. No way he is some government plant, that is lunacy.
I see where the author says it doesn't matter because RP will not get elected but that is a very cynical way of looking at it. RP has grilled some people in washington that other pussy ass politicians wouldn't touch. I believe RP looks out for the people, with what he believes is the right thing to do. He is also a champion of personal freedom, unlike many in washington.
RP was a reasonably wealthy doctor before he entered politics. I have also heard him speak. I believe he truely believes the things he says. He has opened a lot of eyes in the last couple years.
Politicians play us...the two big parties play us. I think Ron is one of the few real people in Washington who doesn't go along with the game.
