When Harris had to pick a VP, all media kinda agreed it should be a white male, to balance the fact that she is black and a woman. So Walz is the DEI hire.
If you ask me, I'm upset no one picked up that this consideration was sexist and racist, although it is indeed the best choice for her to win, which reflects how bad US can't get over race and gender.
Every democratic ticket that's won the presidency this century has been a mixed race ticket. If I had to guess, this election is gonna be a big win for democrats, and if they have any intelligence whatsoever, they'll keep their presidential tickets mixed race for a while in the future. Some people will just always prefer to vote for their own race.
