Trump needs to have a Republican governor as VP. The VP doesn't have to have charisma, as we saw with Pence who was wooden. However, Ben Carson can be entertaining as I saw.
But he doesn't make the CCP, Russia, North Korea quake; Trump does!
Neither could he make the Europeans pay up, as Trump did, re NATO.
And as much as age is being thrown around now, today, in 2028, it WILL again will be a thing! Ben is too old.
