The New York Post reported that even though Donald Trump has said that a future Trump presidential campaign was "highly unlikely," he just spent a lot of money to look into a 2016 presidential run:

...Michael Cohen, executive vice president and special counsel to Trump, told us they commissioned the $1 million in research into Trump’s standing in each state, and to gauge those he would need to win over.

“The electoral research was commissioned. We did not spend $1 million on this research for it just to sit on my bookshelf,” Cohen said. “At this point Mr. Trump has not made any decision on a political run, but what I would say is that he is exactly what this country needs. The turnout at these political speeches indicates his following remains very strong and is growing.“

I'm not sure if Donald Trump is what this country needs, but I do often feel that he's what this country deserves. In any case, all of this is just more of Trump's glory-seeking bullshit. He's never going to run for president, but he's always going to pretend to run for president because it keeps his name in the news. The fact that his machine is starting early this time around—and note that we have no proof that he actually did spend a million bucks on this—means that he's even more desperate for attention than usual.
