Goebbelsian bluster, Werewolf-style. Nothing will come out of it.
Really? It's not as though the extreme right in this country does not have a history of political violence. From the OKC bombing and the spate of black church burnings in the nineties to the Sikh Temple shooting in Wisconsin and the black church massacre in Charleston more recently, this is a real threat. And today these types are far more paranoid, well-armed, angry, and numerous than any time in recent memory. I certainly don't expect Trumpists to actually manage to stage an organized "revolt," but a string of mass shootings and bombings over the next six months would not at all surprise me.
