Well today there is a crawl saying DeSantis has no chance of being on the cabinet, per Trump?
Of course, that could be Klintoon speak for “VP is not cabinet”.
Who knows? Everything is a shake of the bones with Tumpy. It is never by intent or long term design.
So his picks, I believe, are of the moment (much as his governance), and in that, as prescient as drawing a name out of a hat.

It is more from the other direction... That DeSantis would purposefully join to Tumpy as VP, and literally throw fiscal Conservatism, libertarianism, and his battle against the woke empire all to the wind, for the singular sake of advancement - THAT would be a mortal scar.
