Paul Krugman worries about the "Californiafication" of the federal government

I don't always agree with Mr. Krugman, but I think he's got a legitimate concern here about the direction Washington is heading:

And if Tea Party Republicans do win big next year, what has already happened in California could happen at the national level. In California, the G.O.P. has essentially shrunk down to a rump party with no interest in actually governing — but that rump remains big enough to prevent anyone else from dealing with the state’s fiscal crisis. If this happens to America as a whole, as it all too easily could, the country could become effectively ungovernable in the midst of an ongoing economic disaster.
