What poll have you seen that asks people to approve of everything any president does?
I live in a very red part of the country, and in a very red, rural area that voted ~90% for Trump. I don't know anyone that is okay with everything he has done. Some take issue with Venezuela, some with the handling of the Epstein files or the federal budget. Some don't like sabre rattling over Greenland.
Most people I know that do vote Republican are one issue voters. At least here people voted because they always vote republican, support the second amendment, think the republicans actually want a balanced budget, or just hated Clinton/Biden. It isn't about supporting whatever Trump does, though I'm sure some small percentage does.
People regardless of party or region don't think critically often enough and can't set aside their own personal beliefs. We've made our country bipolar and we're seeing the repercussions. It isn't a problem with any one party or person, and the answer isn't to tear down the fundamentals of our system. We need to actually get back to the fundamentals because of late both parties have been going the way of socialism and authoritarianism.
