The whopper of the day comes from Annie Lowrey in The New York Times, here:
Shortly after “taxmageddon,” perhaps sometime in February, the American government will exhaust its borrowing authority – meaning some unprecedented form of government default. It almost happened in the summer of 2011 and resulted in a credit downgrade. Neither party wants to go back there. Expect some agreement to lift the debt ceiling to come along with the deal to delay or otherwise soften the blow of the fiscal cliff.
No, we experienced a credit downgrade because we needed to cut $4 trillion in spending over the next ten years and could only agree on $1 trillion, and if we don't get busy cutting spending more than that there will be more credit downgrades to come.
