I think that celebrities in general are poor candidates in action but make for great poster children. Everyone thinks they know them and what they are like but you only know the public persona. That's what Trump got elected on. Now, more of his personal persona are showing through and people are surprised by his antics. If Trump as taught the world anything its that there should be some sort of public service record at a lower level of power/influence for people running for the job of President. As an outsider, I can see the appeal of an Oprah based on her public persona but how she would handle the pressures of the office? How would she handle the types of decisions that have to be made even if you don't like them? Better to go with someone who has served in a governmental role before that choosing the bright, shiny candidate that you *think* you know.
