Trump's support is based on four major groups: the religious right, the conservative constitutionalists (which is particularly army and secret service based), the openly racist facists and the ultra libertarian minded rich.
One of those groups is gathering pace to openly withdraw support for Trump. The army follow the lead of men and leaders they respect. The American general's are respected by the army in a way that Trump can't compete with, if challenged openly. He's a draft dodger who shat on the graves of servicemen.
At this very moment Trump appeals to the religious right by holding a bible. Not a coincidence.
And he said he'd use the army to please the racists...
But the continuing protests (and covid-19) are costing the libertarian rich too much money. They want a resolution not more conflict - and certainly not the prospect of soliders on the streets of their marketplace, risking the destruction of their property.
He's caught between the priorities and key concerns of his different supporters. That makes his position difficult if any group gets too pissed off.
The Democrats are a complete mess. They don't have much of a clue on how to address key issues either.
But ultimately this election is about how Trump manages to unite his different factions and motivate them to return to the poles to vote for him, rather than alternative.
He's in trouble. He's trying to play different groups off each other, but if he loses the support of a significant proportion of any of those groups he's got a major issue on his hands.
Anyone who in those groupings who manages to put together a solid leadership role to unite that particular grouping against Trump is a big problem for Trump
Imagine if the conservative constitutionalists of the Republican party manage to get behind a figure to rival Trump as an Independent candidate.
It would not surprise me if we are seeing the formation of a potential testing of the waters on this.
