Trump isn't the weakness. The weakness is the almost complete collapse of the checks and balances around the president. If those were in place Trump would have been in prison by the end of 2021 at the very latest.
The DOJ, the military, both houses, the AIPAC wing of the Democrats, and corporate media are all fully captured. So are "independent" organisations like the NRA.
The Supreme Court is mostly captured. The lower levels of the judiciary are still holding out, but have limited enforcement ability without the DOJ.
Candidates come and go but the system endures and it is the system that is rotten at every level all the way down to the core.
Then 4-8 years later the GOP candidate wins subservient to the same interests as Trump and the US Gov is back there again.
Not really sure what the outcome is for the US at this point, things will have to get a great deal worse before enough Americans decide this is unacceptable but that state can last years/decades before the dam breaks.
We need a G. Washington, who refused more power than he was offered, setting precedents and expectations.
Based on recent years and the power of personalized AI influence campaigns, the winning Presidential campaign message (after 4 years of 'change nothing substantial Democrat' would most likely be 'I need real, full (silently: fascist) power, to finally drain the swamp'.
