Paul Krugman’s column on The Dog Whistle deserves to be read by anyone and everyone who professes bafflement over today’s incoherent politics.

The only thing he omits is a discussion of the degree to which anti-Obama fervor is motivated by the color of this President’s skin. But then, that phenomenon is hard to miss for anyone who isn’t willfully ignoring it.

I can’t add anything to Krugman’s dead-on analysis. Go read it.
