Wrong...wrong...wrong! He's very,very intelligent.He is,OTOH,the most amoral President ever to serve.It's vitally important that we not confuse the two.We mustn't underestimate our enemy.
I don't want to discount your point about amorality, but how has he shown his "intelligence" in the four years of being President?
Politically-speaking, I think he's shown he can rule by thuggery. Like a tyrant. He surrounds himself with like-minded thugs. He'd rather rule by decree, than by the prescribed legislative process.
He's not a master politician in the sense that he can forge coalitions; he does not compromise; he's certainly not a statesmen (nor do I expect him to be one AFTER his presidency); he doesn't hold the country above his own self-interests.
If he is "intelligent," as you say, it's only that he can conform to radical poltical exigencies when there is advantage to be gained. He can be a good "front man" for radicals, but when actually called upon to show leadership and "intelligence," he falls way short.
