That would be Obama. His polices are the ones that put us 16 trillion dollars in the hole. Amazing how all the libtards seem to conveniently ignore that fact. A trillion here, a trillion there, and pretty soon you're not talking chump change any longer. The country must repay 16 trillion dollars just to reach broke. Romney isn't in office - Obama is - his watch, his policies, his fault.
$16 Trillion? Boy, the lies just keep getting bigger and bigger as we approach the election.
BTW, the biggest deficit was in 2009, a Bush fiscal year.
The only Obama policy that added to the debt was his refusal to just let the Republican caused crash lead to a depression.
