Paul Waldman, as always making sense:
The message is always the same: Obama and the blacks are mad, and they're coming for you. Yet people like the Breitbart folks and Limbaugh have two problems. First, they're running out of material. There aren't any more shocking revelations to be had. The best they can do is try to make mountains of racial resentment out of the most innocuous molehills, like the fact that Obama supported Derrick Bell's effort to diversify the faculty when he was a law student. And second, by now anyone who can be convinced that Obama is a secret Black Panther never thought otherwise. The guy has been president for three years. Americans are pretty familiar with him. He hasn't actually started herding white people into concentration camps, and it's an awfully tough sell to tell people that he might any day now.
