Which additional block of voters Vance brings in 2024? Much more important is a Trump win, not who will be the VP, who has little functional powers than presiding over the senate to break a deadlock.
Q: Which additional block do ANY of these people bring in?
A: None
Nobody who isn’t going to vote for Trump will change their mind because a woman or a black is the VP pick. It isn’t happening. It is pure fantasy to think it would change anything.
The only possible group that Trump could make gains with would be apolitical young white men who otherwise may stay home. If he had someone who could relate to that group, Trump could theoretically pick 2 or 3 points. Anything else is futile pandering that can only hurt him.
