The nut jobs already feel betrayed by Trump. Because he incited them and indicated (in their braincell) he’d be walking with them to the Capitol... and then didn’t.True enough.
I am not suggesting however that he should not be drummed out of office. Merely that there is no obvious solution.
Unfortunately the "election has been stolen from us" genie is out of the bottle and now not even a Trump statement that he fully accepts that the election was fair and just and that he lost - not that we'd ever get such a statement - would do it. The nutjobs would simply conclude he'd been coerced into making such a statement.
No, unfortunately, he's drummed into them that the election has been stolen from them and they are too nutty to comprehend otherwise.
when even the Trumpistas are turning on Trump (for different reasons to most), you know some really bad stuff is in the offing
