Then why, as badgenome said, did you post a graph of presidents? You're clueless.
That graph extends to 2008, 2008 is the Year the Democratic party took control of both the house and senate. Notice the huge spike? The Democratic party didn't relinquish control of either house of congress until 10/2010 when they split control in the House, and then the House control went to Republicans in 10/2011.
2007 deficit (for comparison - last year of house and senate split) - $500 billion
2008 deficit (first year of full control for Democrats in the House and Senate) - $1 trillion
2009 deficit (Democratic majority in the house and senate continues) - $1.8 trillion
2010 deficit (Democratic majority in the house and senate continues) - $1.6 trillion
2011 deficit (Democratic majority in the Senate, split House) - $1.2 trillion
2012 deficit (Democratic majority in the Senate, split House) - $1.2 trillion
It is abundantly clear which party is responsible in Congress for the reckless spending.
