Well, I apparently owe @icare4america drinks.

Trump/Vivek fits into my model, and I can make predictions around it.

Trump/Some-rando-midwestern-guy-who-will-help-electability (i.e. Another Pence) makes absolutely no sense to me. All of my modeling points to Trump's second term being markedly different, i.e. being a Strong Man, which necessitates him bringing executive muscle into his entourage.

This outcome is really the most frustrating because I don't get the satisfaction of being right, nor do I get the closure of knowing that I'm entirely off-base.
