Does Donald Trump have any power at all?

In a way, it doesn't matter. The cult, which has gotten even crazier with the QAnon thing, will demand unelectable loonies. Sane men and women can't be GOP candidates. 

Yeah, he’s still got an obscene amount of political capital among republicans. Did you see the golden idol of him in his boxer shorts they made for CPAC? 

Of course he does/. You jealous?

the third hydrochloriquine amendment act?

Plenty of his cult members will still throw their money at him on command so there's that.  If he demanded a 2nd insurrection, I don't know what his cult would do.

He never had any real power, as his staff worked out pretty quickly that he is utterly incompetent and pretty much ignored his suggestions.

Trump is just the same as he has always been, a petty man who cheats at golf.

He can order hamberders from Mcdonalds with Grubhub, that's about the extent of his power. 

He said to wait and watch what happens.
