He didn’t suggest it. He asked the question. He is the master troll.
Bullcrap. He ought to keep his rambling mouth shut in this regard. This is provocative stuff and is eroding our nations position overseas. Plus the libs are going to use this in all manner of ad and scare people and own it, guaranteed. He gives them just enough to screw him back with his own careless words and provocations. Individual states of the Union run presidential elections but the federal government so unless he is ready to send in federal troops to enforce it upon the individual states and stamp on states rights and prevent it, he better zip it. Enough of this mans just joking and trolling. Even to suggest such a serious matter is an abuse of his entrusted power.
There are many here who know what The President did here as more than the "fashionable" trolling.
His Tweet says a lot about the rot of our political and journalistic climate.
