Sorry, guys, I don't see where I identified only professional politicians as being qualified to lead, or said that common sense is not desirable. I'm saying that there is more to being a leader than common sense, in fact even moreso in a technology-driven global economy. Are you misunderstanding on purpose? Or re-wording it to change my meaning?
I identified leadship qualities that I think are important:
I think it is important that the POTUS have a thorough grounding in history - American and World.
I think it is important that the POTUS have an understanding of modern technology.
I think it is important that the POTUS have a depth of knowledge about government and law.
I think it is important that the POTUS have an exemplary ability to communicate, both speaking and listening.
I think it is important that the POTUS continues to be curious about the world around him/her.
And I don't care if he/she comes from DC, academia, medicine or sells hats for a living, like Harry S. Truman, who did not graduate college. Truman was an autodidact; he loved to read, especially history. And common snese was his hallmark. He is ranked between 5th and 9th on presidential polls.
