A key Barack Obama Administration legacy item is its wanton abuse of the Constitution’s separation and balance of powers. No Executive Branch in history has spent more time pretending to be the Legislative Branch – writing regulations where the requisite preceding law doesn’t exist.
The Founding Fathers who wrote the Constitution – were by 1800 thoroughly implementing it. If they didn’t yet have the federal government doing something – the federal government wasn’t to be doing it. So unless a subsequent amendment added an authority to the federal panoply – it’s been an unConstitutional addition.
