I honestly cannot imagine anyone deciding to vote for Trump based on whoever he picks as his VP.
IMHO Trump needs to make his decision based solely on (1) who would be qualified to become President if something were to happen to Trump, (2) who would be a legitimate conservative and not a RINO, and (3) who would be loyal and work with Trump to achieve the same conservative goals and not stab him in the back.
Although your points are well taken, there are people that would consider voting for Trump if he picked a favorite of there’s as VP. For example, I know a guy that was a avid DeSantis supporter who would likely only get off his az and vote for Trump if he picked him as Veep.
Personally that’s just crazy in my mind but I think one might be surprised at how common people using criteria like that to make of their mind on a given candidate.
