The highly negative campaign she ran against Obama made many believe that she was attacking him personally not his policies. She crafted a campaign on the wrong assumption that Obama is a caucasian male, and this strategy backfired.
IN those 2 statements you speak volumes, but not to your point. First, negative campaigning is the rule, not the exception. That he is somehow insulated because he is black indicates that he is a quota kid, and not a real merit candidate. Quite frankly, if he cannot stand the rigors of the contest, how can we expect him to stand the rigors of the job? The truth? We cant. Quota kids are always suspect that they got there on gratis, not strength. And it impugns those who indeed make it on merit because we are told to look not at their qualifications, but their "minority" status. In business, that is fine, because should they fail, all we lose is another huckster. In any other profession, where life and death hang in the balance, that is a deadly perception. We cannot trust them because we dont know if they really are the best for the job, of just the most protected.
Second, Hillary has done nothing that has not been done before. I cant stand the woman, and abhor everything about her. But I would be less than honest if I became a democrat just to trash her for running a hard campaign. Nor will I. For what is being done to her has been done to every republican in the last 40 years. Yet no one cared or gave a second thought to it in the past, because they were not a "protected" species.
In the end, Barak cannot win. Not because he may or may not be qualified. But because he has decided (or his campaign and wife have so decided) to run as a quota kid and not as a candidate of merit. He may win the democrat nomination, but that is because he is running in the party of racism and negativism. But unfortunately, the nuclear button and indeed heads of all other nations do not care about America's quota system, but rather the competency of the leader themself. And in that category, Obama comes up way short. It is only when he gets extra points for his race that he is even being seriously considered for the job. That gets him to the ball, but not a dance with the prince.
