Being right on one issue--the war--doesn't make Ron Paul much more palatable as a candidate than any of the rest of the Republicans. He's in favor of dropping out of the UN, eliminating the Department of Education, ending Social Security as we know it, destroying the EPA (counting on the free-market to protect the environment), and dismantling the FDA. To top it off, Paul has outed himself as a creationist.
He says he doesn't believe that the presidency should be "decided on a scientific matter." Of course not. He's a Republican.
