Here are a couple particularly good paragraphs:
"Because when you strip away all of the rage, all of the nonsensical loud noises and all of the contradictions, all that's left is race. The tea party is almost entirely about race, and there's no comparative group on the left that's similarly motivated by bigotry, ignorance and racial hatred."
and
"The tea party is an extension of talk radio. It's an extension of Fox News Channel. It's an extension of the southern faction of the Republican Party -- the faction that gave us the Southern Strategy, the Willie Horton ad, the White Hands ad and the racially divisive politics of Lee Atwater and Karl Rove. It's an extension of the race-baiting and, often, the outright racism evident in all of those conservative spheres."
