Soooo...everything you pointed out/listed is something we can all point out as things OTHER politicians have done?
You're not gaining any support, here.
We all know politicians lie. And it is one thing to have a mistress - LOTS of politicians have done that. But Trump was so accustomed to a certain type of immature, dishonest, and selfish behavior that he was unable to change when he became president.
No modern president has ever, to my knowledge, encouraged his supporters to beat up protestors,
or been videotaped saying the kinds of loathesome things about women that he has,
or so actively encouraged division among Americans,
or derided American veterans (e.g. John Mccain, Alexander Vindman, William McRaven, Stanley McChrystal, Seth Moulton) just because they didn't agree with his politics,
or gone on the kind of Twitter rants that he has (a list:

He is just a fatally flawed individual, from a character standpoint. Sometimes, as in Bill Clinton, say, a flawed president is smart enough and productive enough that they seem to be successful, anyway (although I am no Clinton fan). But I do think that Bush II and Obama are examples of fairly morally upright individuals, on a personal level. Whatever their failings (and I regard Iraq as a catastrophe), there is no evidence of personal corruption, infidelity, or using the US government for personal gain/vendetta. Their communications with the world were well-thought out, dignified, and related to US governmental business,
NOT personal views, anger, disparagements of political or personal opponents.
From your handle, I infer that you are retired from the military. My family is full of military, active and retired, and they report that, among veterans and those in active-duty, Trump is the least popular Republican presidential candidate in decades, precisely because of his
lack of honor and character. His 2020 numbers among the military reflect this:
About half of troops surveyed for the poll said they have an unfavorable view of the commander in chief.

I am sure that some Republicans support Trump for policy reasons - the wealthy want tax cuts, gun rights folks or anti-abortion folks want SCOTUS appointees, or, fundamentalists Christians oppose gay/transgender protections, or libertarians are opposed to universal health care, or mining companies want access to federally protected lands. So, they hold their nose and vote for him, much as many Democrats did in 1996 when voting for Clinton.
But to defend him, as if he were the anointed one - I really don't get that. He is a venal, selfish, and amoral person who lacks the intelligence and self-control to mask his flaws. And, ultimately, these character flaws were his downfall.
