Are Liberals breathing a sigh of relief, now that their Congress has done something not done in 36 years?

Wrong. A fact is something defined as the truth. What you have stated is not a fact, but a lack of reading comprehension. The 111th Congress ped the 2010 Federal Budget in April, 2009. For those unaware, the 111th Congress ran from January, 2009 to January 2011.
