Now this will be hard for the 1+1=POTATO crownd that are collectively known as democrats but I will try anyway.
National debt when Nasty Pelousy took over $8,670,596,242,973. National debt when her cold hand reluctantly handed the gavel over to Boehner $13,858,529,371,601
This is where it gets tricky (for someone that has not passed first grade):
$13,858,529,371,601-$8,670,596,242,973=$5,187,933,128 or 5.2 Trillion dollars in debt.
