Trump's "volatile" and Burgum is the polar opposite from what I've seen.
Little Marco not a good fit in any way I can see.
Same for Tim Scott. Say what you want about Tim Scott, he presents himself as a decent, man of faith and I just don't see a fit between him and Trump.
That leaves JD Vance. A couple years of experience in the US Senate makes him VP material? I think he's a logical guy, well spoken, presents his ideas and arguments well but is he "ready?"
My only conclusion is: it's not really any of the above. It's someone else and it's going to be a surprise.
I would much prefer a conservative Republican who is very well versed in our worthy American heritage AND NOT in public office. We ought not pull people from public offices.
