The only thing that he needs to change is being lax on his response to Antifa and BLM and the havoc that they continue to inflict on our Republic. If he doesn't he will continue to look weak, the thugs will continue to destroy this country and we won't see another election and if we do it sure as heck won't be without conflict and corruption.
Here's the trap.
If he does exert Federal Authority where it isn't authorized by Statute or Constitution, he exceeds legitimate Presidential Authority and can be gigged for that.
These are local matters, with local and State solutions first, and Federal only if requested--unless Federal Property is involved (like the monuments in D.C.) or directly threatened.
While the Press are trying to make it Trump's fault, that simply isn't his job, unless Federal assistance is formally requested by those in the several States and other jurisdictions. He can no more legally send troops to clear out the CHOP or Minneapolis than Bush could send in National Guard assistance after Katrina without the Governor's request.
We saw this same thing play out when he mentioned exerting Federal Authority over Pandemic Response over COVID-19. Not his job, not his authority, for good or ill, it is up to the States and local authorities.
Sure, the Leftists who aren't exerting their authority to stifle violence and end looting, destruction, and occupations, are pointing the finger at him. THAT is the gambit. But it is their unwillingness to take action, ordered 'stand downs', etc. that have ENABLED this level of looting and Civil Unrest in the first place.
By doing nothing they (believe,perhaps even rightly so) that they will retain their positions of power. I have little doubt the political organizations into which donations to the BLM/ANTIFA front groups are being diverted to such campaigns to ensure these willing lackeys of the Communists stay in power as a reward. I would wager those donations are essentially from two sources: suckers, and the Soros led bunch who are billionaires who want control of the Global Government they hope to erect.
I would be all for designating ANTIFA (and BLM, though that would be called "Racist") as domestic terror groups, and treating their leaders/members/financiers appropriately.
