You don't feel how he handled the Covid pandemic was a bad policy? The guy's vanity wouldn't allow him to wear a mask to act as a good example to his base. He blatantly ignored most of what his advisors told him and proceeded to advocate quack remedies and dubious advice.
I really dislike the trope of "all politicians lie" when discussing Trump. It's the worst kind of "what about-ism". I do value a president talking to the American people like we are adults and tell us uncomfortable truths. I think Obama tried that on occasion ands it backfired on him in a major way (comment about those that cling to guns and religion comes to mind).
I do agree with you that it's not solely Trump's fault. The republican party quickly fell into step behind him to get their way above any sort of moral high ground they could have hoped to claim in the past.
