It gets worse.
While Porkulus was sold as an emergency one-time-only program, Harry, Nancy and the 'Rats wrote the expenditures into the departmental budgets -- thereby making the "one-time-only" spending part of the "Current Services Baseline".
As a consequence, when Congress stopped approving annual budgets the next fiscal year, the "Current Services Baseline" took over as the government's budgeting engine -- which would be "last year's spending plus specified inflation factors".
Which is to say that we have now enjoyed the benefits of not one, but FIVE Porkuluses (Porkulii?).
You wonder where those trillion dollar deficits have come from? Look no further than Porkulus -- repeated every year since 2009 (with 5-6% inflation thrown in for good measure).
I have told people that and their eyes glaze over.
