I firmly believe that if any other candidate, in a primary or general election, either republican or democrat, had said this, it would end their campaign.
We have become so accustomed to Trump saying outrageous bullshit, that this will be forgotten in less than a week, and most voters will never even hear about it.
Trump has steadily pushed the limit of what a politician can get away with for years. He is a master bullshiter devoid of any moral capacity to feel shame and bullshited his way through everything. No low will ever be too low for him.
I'm not sure why the senate shouldn't subpoena him, and have him appear before them to explain just what he means by this. He wouldn't show, of course, and end up in contempt of congress. Of course, this would make him even more popular with his cult, but we already know who they'll vote for.
Really, he keeps doing shit that would get anyone else arrested. It's time to arrest him.
It's easily forgotten because he'll say something new and outrageous again next week. Even his voters don't know what he intends to do. They just get caught up in whatever word salad they attach to.
In reality, he will probably not do a fraction of the bullshit that he spews as promises. He has never kept a promise in his life anyway. He's not starting now.
Last time he was president all he did was golfing while letting bad guys run wild. He's enabling "chaotic evil" by being an idiot.
For instance, the pathetic half-assed wall didn't solve the immigration issue at all. The real evil were the stooges organising ICE to encage children.
It is not random. He has a group of people doing a deceptively good job crafting the message for each region. Just like he did in 2016 with Cambridge Analytica.
He, himself, is a barely coherent idiot, but I think it allows their message to be received by people who also don't have that good an education.
E.G. find one of his speeches from the rust belt. They're all fairly similar. Will hit notes of corruption, proud people, fight the NYC and California democrats that did this to them, anti-trade and protectionism, etc. Then go find one like this one that was to bible belt extremists. Completely different. Will still hit some common notes(NYC/Cali), but the underlying message and theme are miles apart.
Edit: to be clear, its all bullshit lies that are telling people exactly what they want to hear.
Other people organized, staged, and enacted that coup. When he realized it was happening, he decided the coup stagers were "loyal" to him, so he was on board from that point on.
