i just don't see trump ever doing anything to "clear things up" unless it just happens by accident, like most anything good that comes from trumps administration, purely by accident
Could well be accidental, but the revenue potential doesn't lie, and to a politician more revenue is a bigger trough to stick their noses in.
But, as said, do it right and you save a fortune on petty possession charges, save court time, save prison time, that's all costs from revenue so there's a hell of a saving added to the potential extra revenue which, in reality, could be at least partially used to help against the real scourges like meth, crack, smack, "other opiates", etc.
That's the angle I'd use in his place, as narcotics and the economy are two major issues, so there's revenue PLUS "being seen to be doing something about the real curses on society".
Plus he'd annoy the shit out of people in every aspect of politics,.wouldn't you enjoy doing that?
