Well, as a president not yet. If the Democrats are beaten in the next election to a pulp and if the powers that be are defeated sufficiently - he'll easily be among or the best president of all times. It really depends on what he can accomplish 2020-2024, and I hope he'll rip open some asses as he doesn't have to give a flying fuck any more.

His work is not done yet.

As an entrepreneur however, sure - he is a billionaire, and that's a sign of extreme levels of competence and respectable work. That doesn't need praise though, he is generously paid for that.
