From a 2021 article it appears he lost white males and picked up more white females:
“According to the Pew analysis, Trump won white voters by 12 percentage points, 55 percent to 43 percent, down from 15 points in 2016. Biden narrowed Trump’s margin among white men — from 30 points in 2016, to 17 points in 2020 — but Trump won white women by a larger spread (7 points) than he won them in 2016 (2 points).”
And regardless of what polling shows, any Republican will lose if the fake votes keep getting counted.
An ABC News/Ipsos poll, in the field April 6 and 7, showed that Trump’s unfavorable rating climbed to 61% from 55% a week prior. The former president’s favorability rating sank to 25% from 29% in that period.
In the same poll, 80-year-old Biden’s unfavorable rating fell slightly from 49% to 48% and his favorability rating rose to 34% from 32%.
An Economist/YouGov survey that polled Americans April 1-4 found that Trump had a 51% to 44% unfavorable to favorable rating, while Biden’s spread was 49% unfavorable and 45% favorable.

I’m sure Pew’s data is right, but the only states that mattered regarding that data, were Georgia, Arizona, Wisconsin, Michigan and Pennsylvania. I’d like to see their numbers in those five states. Picking up more women in red states is immaterial to which states cost the election
