"...so tea party Republicans seem to be learning that the public won't tolerate defaulting on the national debt." Of course they won't. ...but they are collectively deluded (with help) enough to think that failure to increase the debt limit will result in defaulting on the DEBT...the SOVEREIGN DEBT.
That is horse hockey.
Maybe they don't know the difference between debt and spending plans. If the debt limit is not raised, we WILL NOT DEFAULT. When the apocalypse does not occur, even the fawning media will be unable to conceal that fact.
So bring it on.
