If there were one politician to whom you could address personally, face-to-face, who would it be, and what would you say, ask, or demand?

The late POTUS Ronald Regan, is who I would want to talk to, and thank him for what he did for our country.

Unfortunately, like all narcissists, it is impossible to hold a conversation with them. Because they are unagreeable, completely non-understanding & they only believe they are right, no matter what we say or what evidence we provide to them.
The best thing I learned it is to not waste my time trying to argue with complete idiots. They don't even understand their own job! I have much better things to do with my time, that's for sure!

Any of the Founding Fathers. I would ask for them to explain the Constitution and Bill of Rights (10 Amendments) in layman's terms. Then I would watch as they looked at me in a puzzled fashion - and finally say - it already is in layman's terms.
