I never cease to be amazed by the thinking among the punditry that Ezra Klein is some sort of whiz kid. It seems to be one of these ideas that gained momentum for an unknown reason and just snowballed. You read his "Wonkblog" in the Washington Post, you see his TV appearances, and he comes off as that smug, prissy liberal who is always raising his hand in Political Science 305, and is way more impressed by his own rudimentally knowledge than he ought to be. But everyone keeps muttering about how "bright" he is even as you shake your head and wonder what's making them say that.
