KellyAnne Conway in a recent interview referred to the president-elect as "the President". The host corrected her that Trump was not president yet. I have heard some of his more fervent supporters make the same "mistake". 
This assumption to power follows Trump's need for it. I listened to his Orlando "thank you speech" and noticed his segment on being picked Time's "Person of the Year". That seems to have upset him. He then used his audience to confirm his thinking so as to deflect that it is only his concern.
He sets up the issue as one of being politically correct, being named "Person" rather than "Man" of the year. Note that when starts the audience cheers "person" but he leads them to perfer
Though "person" means everyone, he'd rather have been "Man of the Year" even if it covers half of the people.
Watch what he says about a possible woman pick: "Person or Woman" of the year. But for him "next year" is has to be Man of the Year.
