If I was 18 I would probably vote for Ron Paul, I am however older and wiser now, and see what a kook he is. Utter political slime ball piece of dog shit, with the foreign policy of a 15 year old. Guy is not anything like he is portrayed to be. He consistently has earmarked spending for his districts added to 'must past' bills, and than makes a show of voting against them on the floor.
His foreign policy is the equivalent of saying fuck you too all our allies, and leaving them out in the cold. He will essentially ruin most of the United States favor with our allies for years, years when we may want some one on our side in a global issue.
The fact is, the planet has been globalized, Ron Paul's isolation policy would have worked alright in the 19th century, and early 20th century, but have no place with a developed nation in the 21st century. He is your crazy uncle who's head is a little more then a bit off axis.
