That's his approval now, not in 2020. He was more popular than unpopular until August 2021. Also, there were people who voted for him who just wanted Trump out and weren't that enthusiastic about him. Also, opinion polls include a lot of people who have no opinion. Those are the people who stay home on election day.
The country is polarized into 40 % lefties and the rest want their country back. It does not matter of its 2020 or 2024.

What you and others do not understand is that if the cheat continnues, then it is a recipe for disorder and violence. America will not accept the ruination of the nation at the hands of an illegal, extortionist socialist minority.
So it really does no tmatter how many mega donors desert Trump and go for more control of the national agenda. Good riddance to them all.
THe TRump grass roots will outfund them all if necessary.
