Not gonna read, but you know how I feel about these... they float an idea, won't get it, but then the idea is out there for the future.
That said, here is my take given that this is part of his BUDGET proposal and not something put forward by Congress: OMB is COMPELLED to calculate any surplus/deficit in anything they review using the numbers given, period. So Joe's awesome ideas run up an even more massive deficit... how does he offset that for the OMB calculation? Put in a ridiculously massive tax that offsets said spending, VOILA! Then Jim Jordan has to run around to all the Fox shows saying "HERE ARE THE REAL NUMBERS WITHOUT THAT TAX THAT WILL NEVER HAPPEN!" Then we have to hear the Dems run around and say, "THE OMB SAYS NO DEFICIT!!!"
Stupid and doomed.
