It's not a good short term strategy at all. If that's really the goal, their left and right hands need to have a chat because one of them's going to make the deficit way worse, so if the other's goal is to "free up operating budget" by reducing debt service they really ought to get on the same page, because anything "freed up" is going to be eaten by the other bullshit they're doing.

Besides, this is a wildly expensive way to go about it. The harm to receipts from the economic uncertainty will blow a hole in the federal budget and leave states reeling (to say nothing of the "other hand" making cuts at the IRS, which will also be a net cost)
