Check the card he's handing out at rallies.
(And don't forget him sending Christmas cards to all New Hampshire voters)
That very excellent and clever card is a great way to work off of that investment. He's already long-established his "brand."
Remember please that Trump's fame is purchased and crafted, it always has been. Bestowing credibility on someone because of a brand they have promoted for a decade is bad business. The idea that, "Well, he's a billionaire, that's proof enough that he knows what he's doing!" in the face of Trump's documented past political inclinations, is based on media imagery directed by The Donald. Otherwise no one would know his name or face.
Just remember it, because truth is important in perceiving the best actions.
