Here's S&P from Bloomberg Business News:
{Raising Taxes
S&P, though, noted in its report that the failure to act on raising revenue also was a consideration in its decision.
“We lowered our long-term rating on the U.S. because we believe that the prolonged controversy over raising the statutory debt ceiling and the related fiscal policy debate indicate that further near-term progress containing the growth in public spending, especially on entitlements, or on reaching an agreement on raising revenues, is less likely than we previously assumed,” the company said.
S&P also changed its assumption that the 2001 and 2003 tax cuts enacted under President George W. Bush would expire by the end of 2012, “because the majority of Republicans in Congress continue to resist any measure that would raise revenues.”}

I don't understand why people think our rating has been correctly AAA since the Reagan years. We shouldn't have trusted S&P's rating in the first place (the way we shouldn't have trusted their CDO ratings) because the U.S. was at the heart of their conflict of interest.
When Republicans started to believe their voodoo economics is when we should've first lost our AAA credit rating.
