What people are looking for, when they are a President or a Governor picking those who are going to be their closest advisors are competent, qualified people that they trust. So they are usually selected from people they have worked with and know, rather than at large.
I have a hard time believing that there are many who become Governor who look around at their friends and find only couch potatos and highschool dropouts. People at that level usually have a long professional association working with others of a similar caliber. They have friends who run businesses, have their own political careers, etc., and those people usually wind up in their cabinets.
That Romney's circle doesn't include any qualified women...
