The S&P obviously by virtue of their claim of lack of confidence are not interested in political jousting.
In my opinion there is nothing Obama can do or say to restore the earned lack of confidence to earn a restoration of the AAA rating.
Just look at the circus of the last few weeks.

AAA ratings are the most coveted of all ratings...government or corporate wise. A corporate leader losing a AAA rating would be out of office Monday morning.

The issue is not R or D....it is not taking responsibility and doing what ever it takes to preserve the stature of this nation.
The politically acceptable in Washington has just been notified that it is financially unacceptable to those who understand the reality of FAILING to be financially responsive.
