Mr. Roberts is very, very, smart. He is magna cum laude from Harvard, literally #1 in the class, smart. And if that has gone to his ego, that could be a achilles' heel, as he leans towards decisions that are more marked by cleverness than conservatism. When in the SCOTUS, precedent means squat. They *are* the precedent.
BTW, Summa cum laude is top in the class, magna cum laude is with much praise but not "literally #1". Smart he may be but that is only an elemental credential as far as I am concerned.
