While I agree with much of what you wrote the percentage of people supporting every (or even most) decision of this administration is very small. But a large portion of the population doesn't like the alternative any better.

They said a few years ago that Trump and Biden have a chance only if they run against each other.

So it is more nuanced. We will see what the candidates in 2 years look like.

The vote is skewed because of the large number of Latinos and East Asians that have flowed into the country over the last three decades. If you tally the vote by ethnicity you'll see there's a large amount of support from the white majority (which is getting smaller every year) for these measures.
