Not a big Trump fan, but he has an advantage that none of the other candidates have; He can say what he wants to say. From a purely entertaining standpoint, a Trump/Hillary election would be a hoot, a Trump/Sanders would be even more entertaining.
He stays on topic, shows little respect for the current state of open discourse and takes very popular stands. He could win if all fell into place. I have to admit, a Trump administration has a certain charm, a certain ring to it. If just to make the Libs heads blow up!
