He is unknown by design.
He is the blank screen upon which peoplr project their views.
He is all things to all people.
He is everything and he is nothing.
His past is even spottier.
=========================================
The guy has published TWO BOOKS about his life and times. You have, I am guessing, read neither.
Every magazine in the nation that deals with news and politics has written about him in great detail. Doesn't seem that you read these, either.
His agenda is end the Iraq War, provide health care, restore the Constitution, use inspiration and hope rather than fear and greed to lead the people rather than herd them like livestock. His agenda is quite like that of every Democratic candidate that has run in the past four elections.
This is just a way the Republicans have of saying: "imagine you are a half-African man raised in Indonesia and Hawaii by White folks".
They are counting on the undecided voters lacking enough imagination to do this: White people have no clue as to what it is to grow up and live as a Black man in America. They should be afraid. Very afraid. What would a Black man do to someone aware of the vile racists jokes they have told and heard and laughed at?
So they should stick with McCain. We know who McCain is: he is Rambo, he is Chuck Norris, he is the daring flyboy in a hundred Hollywood epics.
Not so much the spoiled Admiral's flyboy son who got himself shot down, was held prisoners for years, came out, divorced his crippled wife, fooled around like Casanova, found a rich heiress, married her and pretended to be an Arazonian.
