I think that because of the massive Democrat lead in the populous states, Trump doesn't even need to win the popular vote to win the White House. If he's leading nationally, he could get 350+ electoral votes.
Yes national
No, you can’t read it like that. Trump could have picked up an extra million votes in 2020 and still “lost”. Trump may very well pick up some minority votes but if they are primarily in NY and CA ghettos it’s not much use. The black support needs to be increased in Atlanta and Philly. Hispanic votes can’t be concentrated in Florida but needs to be increased in Az and NV.
