Paul Krugman's NYT essay argues that the Republican party has primarily been led by and founded on racism. That's a deeply serious accusation. Krugman needs more evidence to make such a claim. Certainly, racism has been more prevalent in the GOP. But Krugman is claiming that the conservative message of "anti-government" is really a proxy for anti-black. That's a stretch. And possibly a direct insult to the numerous black members of the Republican party.
