Instapundit noted the US Government ran a 1 billion dollar surplus last month, mostly due to increased tax reciepts from corporations. I've always maintained the deficits were controlled by the success or failure of the economy to grow, and this definitely seems to be proving my point.
As far as the CBO's 5-year and 10-year predictions... well, if someone can show me a case when any of them were ever actually correct, I'll start taking them seriously.
