Steve Benen has a timeline for us today. I'm just going to steal the second half:
September 2010: In Obama's first fiscal year, the deficit shrinks by $122 billion. Republicans again condemn Obama's fiscal irresponsibility.
October 2010: S&P endorses the nation's AAA rating with a stable outlook, saying the United States looks to be in solid fiscal shape for the foreseeable future.
November 2010: Republicans win a U.S. House majority, citing the need for fiscal responsibility.
December 2010: Congressional Republicans demand extension of Bush tax cuts, relying entirely on deficit financing. GOP continues to accuse Obama of fiscal irresponsibility.
March 2011: Congressional Republicans declare intention to hold full faith and credit of the United States hostage — a move without precedent in American history — until massive debt-reduction plan is approved.
July 2011: Obama offers Republicans a $4 trillion debt-reduction deal. GOP refuses, pushes debt-ceiling standoff until the last possible day, rattling international markets.
August 2011: S&P downgrades U.S. debt, citing GOP refusal to consider new revenues. Republicans rejoice and blame Obama for fiscal irresponsibility.
Congratulations, modern Republican Party! That was spectacularly fast work. The Bush-era party needed seven years to drive the economy into a ditch.
