I don't think that those people are as much a minority as you think. I'm not saying they're the majority, but it's a sizable amount IMO.
I agree. I know plenty of know nothings, who spout the most ignorant nonsense, and claim to be tea party. Never underestimate how many dumb rednecks there are in this country. Most of the intelligent people I know, who are interested in smaller govt claim to be libertarian.
