DeSantis would be a better choice as a VP because he would have the ability to win after Trump's term. People vote the top of the ticket, nobody votes for a ticket because of the VP. Even a DeSantis/Cruz ticket would be a winner over Biden/Harris or most RAT tickets.
Cruz is Hispanic and they are currently trending more conservative than in the past. Cruz as a VP could, maybe, bring in even more Hispanic votes. However, I am not sure if he is bilingual? If I were going to go for a Hispanic I would want one with strong ties to the Hispanic community. Noem does not look as politically good as she did a year ago. No way in hell would I go for Haley as a VP either. Christie is an idiot's idiot and Bush is just another "Bush league" Bush. None of the above except for DeSantis as VP could win after the Trump Presidency. GOP does not a lot to choose from right now hence Cruz is still in play as a VP.
You are correct that most do not vote for the VP, but I will not vote for Trump if he picks the ineligible Cubanadian.
More presidential?
Oh, ya mean more presidential like the corrupt lawyers turned career politicians, posers, insiders, liars and open borders globalist that we've had going back decades?
