The president claims to be a “constitutional scholar”. If he doesn’t like the second amendment he should propose and lobby for an amendment to modify the language of the second amendment or repeal it entirely. We can have a national debate. He and the teleprompter can go on the road campaigning for his amendment. Let the people direct their elected representatives how to vote and put this issue to bed once and for all.
He doesn’t do this because he knows an amendment cannot pass the House and likely would not pass the Senate, much less the state legislatures. For this reason, it would be good politics for the NRA and others to demand he put up (i.e. propose and amendment) or shut up.
There is a difference between “knowing” what the Constitution, and actually “caring” about what the Constitution says.
He doesn’t care. Period.
