The point here is not so much the $2 trillion, which makes very little difference to real US fiscal prospects; it’s the fact that S&P stands revealed as not understanding basic analysis of budget estimates. I mean, I don’t think I would have made that mistake; real budget experts, like the people at the Center on Budget and Policy Priorities, certainly wouldn’t have.

So what we just saw was amateur hour. And these people are pronouncing on US credit-worthiness?
