Racism is often the last resort of a liberal.

We saw an example of this from comedian Janeane Garofalo, who wouldn't deserve attention as an analyst unless she provided such a perfect example of liberal racism. It came in an interview where she was talking about GOP presidential candidate Herman Cain

Take a listen: "Herman Cain is probably well liked by some of the Republicans because it hides the racist elements of the Republican Party. Conservative movement and Tea Party movement, one in the same."

This is racism pure and simple. It implies that Cain is either an idiot, or a willing participant in a fraud to cover up racism among conservatives. It also implies that African Americans need white liberals to tell them what they should think. Those African Americans who refuse to bow to the rules of the liberal plantation are either idiots or sell outs.

That a second-rate comedian would pass such judgment on a man who has had such an extraordinary career as a Navy mathematician, a Fed governor and a successful businessman should probably not be taken seriously. But it just got under my skin -- as racism always does.
