In 2020 election, Trump increased percentage of votes of EVERY ethnic minority comparing to 2016 despite being labeled as a racist. Biden lost votes of every ethnic minority in term of percentage.
Ironically, in 2020 election, the only ethnic category Trump lost (again in term of percentage and compare to 2016 ) is the group you call racist, white men. Yes, Trump even gained white women votes in 2020. Trump lost 8% white men votes. Since white men is the largest category, base number is huge. We can say from your logic the racist white men defeat Trump and elect Biden in 2020.
What you really don't understand is the racist claims have only strengthened minority resolve to support Trump. We will see it again 2024 regardless of win or lose by Trump.
