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.
