Do looks and speaking manner cause us to pass over great minds for political office?
Oh yes. It is too often more about the messenger than the message.
If a person does not dress well, cannot speak well or isn't very nice looking people tend to dismiss them as not favorable politicians even though their mind might be fantastic. We should allow a spokes person to represent these people and we just might have a better government. My cousin did not present himself very well but he was a genius and he did well at Lawrence Livermore Labs with a person who actually lived with him and explained what he was thinking on various matters.
That’s true... but, one politician defied all that. Trump is not attractive, well groomed nor does he speak well.
