What is a joke about hiring experts in each field rather than trying to pretend you can do/know it all?
He is a guy, but it looks like he is pretty smart too.
Simply the fact that he is a movie star, and seems to be picking advisors who are actors or the subjects of movies, makes one of his weakest points (that he is a celebrity, and not a typical *spit* politician) and exacerbates it. It also paints Arnold as someone who lives in the movies rather than in reality. Other pols have had celebrity advisors, but certainly not to the same percentages or numbers as Arnold has thus far.
(and you can't seriously think that Rob Lowe is the top in his field, or has led an inspirational life)
