Be sure you understand who Ron Paul is before you decide to vote for him. Some Libertarian platform planks (like ending the war on drugs) are attractive, but putting a racist homophobe who is against women's right to choose is a very bad idea.
"But, whoever actually wrote them, the newsletters I saw all had one thing in common: They were published under a banner containing Paul’s name, and the articles (except for one special edition of a newsletter that contained the byline of another writer) seem designed to create the impression that they were written by him--and reflected his views. What they reveal are decades worth of obsession with conspiracies, sympathy for the right-wing militia movement, and deeply held bigotry against blacks, Jews, and gays. In short, they suggest that Ron Paul is not the plain-speaking antiwar activist his supporters believe they are backing--but rather a member in good standing of some of the oldest and ugliest traditions in American politics."
