Correction, I have found a difference between the two candidates, and I'm quoting someone who posted a comment on YouTube:
1. Drug policy: Barr got defeated for Congress because the Libertarian Party ran ads saying he strongly supported the war on drugs. Many guys would
get put in prison for months for simply smoking a joint. This was when Barr was in congress.
2. USA PATRIOT ACT: Barr helped write in, Paul's against it.
3. Gay Marriage: Paul supports civil unions, and slow but ultimate equal rights. Bob Barr co-wrote and fought hard for the "Defense of Marriage"
act.
