The Great Society was one of LBJ's most destructive political maneuvers on our society, so I don't see that as irrelevant. At any rate, you brought him up to begin with not I. This thread is about the First Lady. My reaction to a derogatory comment about her is when you commented and compared Trump to LBJ and JFK....which really was off topic.
IMO, it takes second fiddle to:
Barack Obama's political maneuver....Open Southern border and conspiring with HIS Homeland Securty to allow the flood of Muslim single men from? Who the hell knows?
The Obama Administration, by itself, is at the top of any list in terms of a destructive political maneuver to our society.
