That is because Trump actually put in the hours to be a success. I was not a Trump fan originally. The more I saw how he worked his ass off to win the more I liked him.
I would expect him to do the same as president. He may screw up from time to time but it ain't gonna be cause he was out golfing. The US always seemed to come up with the exact president we needed at certain key times in its history. This is one of those times and I think Trump will rise to the challenge. 
Man, I'm banking on it myself.
I hated the guy in the beginning, didn't like the way he campaigned and I'll leave it at that.
But he quite obviously plays to win and sure as hell isn't afraid to stick his neck out when he needs to.
I'm sure he'll piss me off more than once along the way, but I've got a pretty good feeling so far about his motives in general.
