Why the 'current policy' baseline is a massive gimmick that effectively kills the filibuster

Julian Zelizer : GOP using "current policy" budgeting to avoid the cost of extending tax cuts.

He says the tax cuts will cost $4.6 trillion over the next 10 years if they're extended in full with no spending cuts to offset them.

Zelizer says GOP could use the same gimmick to pass a "Medicare for All" bill that would cost $10 trillion .

A more deliberately opaque budget process that opens the door to more spending and kills the filibuster is a path to even less fiscal responsibility and a recipe for more borrowing. This is a mistake on its own, but it looks even more foolish because that "current policy" baseline puts the federal government on course to borrow about $30 trillion more by the end of this decade . You can't ignore your rent payment, spend the money on other things, and assume it will all work out, but that's exactly what Congress is poised to do—and the cost will be added to an already towering pile of debt..
