Qualifications for the office of the President in the last century were so very very different. Of course he is more qualified than Abe was and Abe would be the first to tell you that. Obama claims an expertise that is strictly academic, not that we have access to his academic information. He has never been tested as a human being, not on a real job (ever), not in the military, not ever. We know absolutely zero about his metal under pressure. We cannot afford the OJT (on job training, for you youngsters) with our very existence as a nation in question. It is a mistake to believe that what exists now will always be. That is the mistake that defunct kingdoms have made for thousands of years.
