The Tea Party wants to default and no amount of expert opinion will dissuade them. Obama is trying to explain these things to them, but that just makes them angrier. Wall Street is trying to explain things to them, but they won't listen to them either. They're like zombies. They don't want to manage the government, or make it more efficient, they want to destroy the government. Small wonder that they're making a mockery of the way the system is supposed to work in the process. They don't seem to realize that they have to win elections before they can impose their agenda.
I'm sorry to see that the Republican party has been thoroughly consumed by this movement of populist stupidity. I'd feel much better as a Republican if we could be rid of their movement even though we'd have total Democratic control of government. The Dems at least have a bigger tent and don't have a pathological fear of informed opinion.
