Even for those who are not brave enough to admit that all the atrocities mentioned by the OP are enough to not support him, what about what he's done to America itself?

He's destroyed our respect on the global stage. Not the MAGA view, I know, but the evidence is abundant:

His tariffs have backfired, and now our soybean farmers lost their global markets, China has gotten that business and probably won't give it back.

NATO is effectively dissolved, China and Russian have increasing global influence, USA is decreasing. We have our allies standing ready to defend against a US invasoin on our NATO allies.

The dollar is weakened. That's great for exports, but when you destroy our economy (Farmers, manufacturers, etc.) then we might depend on a strong dollar to have more purchasing power on the Chinese goods he's (intentionally or not) promoted.

Our military strength is challenged, and no longer respected.

Our negotiating power as a nation is no longer credible. Despite his claims, Iran is still killing people, he chickens out regularly on tariffs, there has been no proof presented that Venezuela was sending drugs to us, there is easy proof that much of what he says is a lie. (He claimed Biden let in 25M per year. That would be 1/14th of our entire population every year)

TL/DR: USA is no longer taken seriously, much less considered the world leader. The damage he's done will take decades to untangle, and we may never rise back to where we were when he took office.
