All I know is, I figured out a long time ago that Republicans talk about small government a lot but when it comes time to deliver, they do just enough to claim they've saved us from those pesky Democrats. In reality, they're both big government and the GOP is just less so (ever so slightly) and in slightly different ways. Dr. Paul votes no on new legislation so often he earned the nickname, "Dr. No" in Congress. He almost always votes no on things that according to his (which is very close to mine) reading of the Constitution, Congress does not have power over.)
He might be a little "weird" but I've always preferred weird people over those who smile a lot and then stab me in the back. And unlike a lot of people who talk a good game in , he has a Congressional voting record of, what is it now? 10 terms, to illustrate he does what he says he does.
