Inside the debt deal negotiations

There have been two articles about the debt ceiling negotiations last summer between the President and the House, one in the Washington Post, and the other in the New York Times. The former seems to suggest it was the unfortunate timing of an announcement by a bipartisan working group in the Senate that caused Obama to backpedal, feeling he couldn't agree to more spending cuts and fewer tax increases than the Senate. The latter article implies on its first page that it places more blame on House Republicans.
