I think I understand your point, but 75% of Americans are white, so it’s not surprising that the majority of Tea Partiers are also. If you filter in a bias toward middle class and employed or employable, and more educated, you’re going to end up with an older demographic as well. In this country, those qualities will also give you a whiter one, but in other countries (Japan, say, or India) it won’t. I’m sure the middle class in any country would be particularly incensed by a meddlesome, confiscatory government. Race oughtn’t to enter into it.
