Sorta like a RETRO Line Item veto...
Can you imagine the reaction if a Republican president came out with anything like this.
I can just picture Chuck Schumer on the Sunday talk shows, with a grave expression on his face, intoning something like this: "under our Constitutional form of government, the President doesn't get to decide which laws to enforce and which laws to ignore. One would think that a President who claims to have been a Constitutional Law Professor would know that."
But when a Democrat is in the White House, it's more like "hey, that's cool."
