Here's a good quote from a Tucker Carlson article which sums up most of Paul's positions really well,
Though Paul argues passionately for liberalizing marijuana laws and is beloved by potheads (Timothy Leary once held a fund-raiser for him), he has never smoked pot himself. He sounded shocked when I asked him. "I have never seen anyone smoke marijuana," he said. "I don't think I'd be open to using it." For some people, libertarianism is the philosophical justification for a zany personal life. Paul, by contrast, describes his hobbies as gardening (roses and organic tomatoes) and "riding my bicycle."Here's the first part of the Stossel interview on YoutTube:
He has never had a cigarette. He doesn't swear. He limits his drinking to an occasional glass of wine and goes to church regularly. He has been married to the same woman for 50 years. Three of their five children are physicians.Ron Paul is deeply square, and every bit as deeply committed to your right not to be.
"I don't gamble, but I'm the gambler's best friend," he says, boasting of his support for online casinos. He is a Second Amendment absolutist who doesn't own a gun. "I've only fired one a couple of times in my life. I've never gotten around to killing anything." It's an impressively, charmingly principled world view,..[link]
