If Trump croaks, will they actually tell the public?
They could simply pretend he is alive and well and issuing orders- they could implement their agenda without the madness, without the tweets- video could be computer generated to make it look like he is alive and well... Putin would be notified before Melania, I am sure....
We could have a whole "Weekend at Bernie's" scenario going on in the White House... hilarity and crimes against humanity would ensue....
