So true:

This gets at the heart of the current pundit problem. If you say that one of our two major parties has gone completely off the deep end, you're considered shrill and extreme. But if you don't say that, if you pretend that someone like Barbour is a reasonable guy with somewhat different views, then you're fundamentally lying about reality.

So true of the Conservatives.

But actually written by Paul Krugman about the Republicans.

But they're related in being out of their depth in an extreme deep end of their own making.
