Neil has an interesting analysis of "why Congressional Republicans are taking extreme bargaining positions that shut down the government and risk defaulting on debt." He points to Republican "primary problem, which "makes Republican officeholders do the crazy things that the Tea Party likes, because they fear losing their primaries even more than they fear losing the general election." This has it backward in two important respects. First, it fails to understand the rationality of the Tea Party caucus. Second, by demonizing the Tea Party as "crazy," it facilitates the far more dangerous tendency among educated people to grow impatient with democracy and pine for rule by experts.
First, since 1988, the Republicans have won the popular vote once: in 2004. Their House majority is now primarily a product of gerrymandering and superior mid-term turn-out. If you look at the congressional Tea Party heartland (see this good map at the New Yorker), it is primarily rural, elderly, white, and Evangelical. With the exception of 'Evangelical,' perhaps, this is not the future of America. And even born again America is remarkably fluid when it comes to so-called 'life-style' choices--the generational shift of opinion on Gay Marriage has been phenomenally fast. That is to say, these are folk that know they will loose national elections time and again. Obviously Republicans can still put together winning national coalitions, but as the Tea Party heartland learned under the three Bush presidencies, these will not reflect their values and interests. They are not acting as co-partners in government awaiting their turn at the helm, but as the legal opposition. They are playing a lousy hand superbly and -- best of all -- by democratic means. That's not crazy.
