This can either be the impotent rage thread, or we could discuss this as if it was a tactical move rather then that of idiots who somehow run America.
Okay then, I can get behind this.
Do you think the Tea Party's showing in the House considers this to be brinkmanship, or do they honestly want a default if it means shutting down the ACA? In this light, the former is likely true, because the latter would also mean a serious blow to things they actually like. I think what will end up happening is that Boehner manages to shut them down at the last minute, and pass something to kick the can down the road by a few months. From there it's just a question of how far. If the Tea Party, or Republicans in general for that matter, do well in 2014, it could mean that they could push the issue more effectively, but at this juncture I don't see that happening easily.
Misko made a good point a few pages back. These people are not representing everyone in the country, they are representing the people in their own districts who sent them to Congress on their behalf. I don't have the numbers in front of me, but IIRC they are still reasonably popular there, where it actually matters. At least more popular than anyone who runs on a democratic ticket could hope to be. They MIGHT be ousted by another Republican but that wouldn't make much of a difference for our purposes.
