But the debt Obama ran up was different you see. That debt was necessary to correct the mistake of George Bush of running up too much debt and sinking the economy.
We had to go into more debt in the Democrat admin to fix the problem of the debt we ran up previously in the Republican admin. Apparently now running up even more debt in a new Republican admin is a bad thing, where it was previously a good thing covering the bad thing that happened before it.
Only Republican debt is bad debt according to Democrats. Those debt dollars magically transform from President to President.
