Hahahah. Yeah, that too. Although I'm sure Trump detractors would point out that this is a small fraction of his fortune, and argue that what is ultimately driving him is nothing but his own vanity.
I'm a Trump supporter, having watched his remarks through the years. Yes, he has a clownish and media side. But I believe he is serious about this endeavor, and I believe he is not doing this just for self interest. This is a deal. And good deals are win-win. Of course he gets something out of this. It's huge from an ego standpoint. But I doubt he wants to be known as a president who grossly misrepresented his intentions. What you see is what you get. I don't necessarily like all I see, but I do appreciate getting a chance to see it, unlike the usual political process of talking in code and hiding the ball.
Perhaps Trump didn’t see a future for his family, with the trend of the country. Sure, if you have wealth, it seems from the street vantage point possible to move to greener pastures. Perhaps that isn’t a viable option from his vantage point-—standing up for a change of direction was the only course.
He’s had success in business—likely intends to pass the mantle to the children. For this possibility to come about, the country cannot continue a decline, business as usual is a losing proposition. This realization forced him to finally do something, which until now he managed to avoid-—running for office.
