Understand something:
Trump. Is. NOT. Running.
He can give speeches all he wants, but he hasn’t filed with the FEC as a candidate for President, and he isn’t going to.
As he always does, he’s going to milk this for a lot of publicity, and then drop out. He has no constituency, and he knows it. He doesn’t want to be President- he doesn’t even want to campaign. He just likes attention, positive OR negative.
