I think you are off base. There are many of Trump’s campaign promises that will need to be implemented jointly by the States. Every Governorship counts. To return education to the States & communities, dethrone Common core and facilitate charter schools will take a group on the same page.
if this bizarre little theory held any water at all, he would have offered the UN ambassadorship to the governor of a purple state that had a democrat governor and a republican lt. governor -- where he would actually (possibly) accomplish something.
there are some people on FR that need to dial the weirdness back a few clicks.
