He is a chameleon, shedding masks.
We knew his background and political history when he first ran for President. Then he presented himself at the 2008 Convention as some Roman God and his followers fawned over him. Remember the "faintings" in the audience and his calls for help?
It's just my opinion but I believe most Democrats, including a majority of black voters, figured he was a sure winner. Regardless of his lack of credentials, some of those who did not vote for him were, of course, called racists.
Well, racists can be found among all nationalities, races and religions. Did 95% of black people vote for him because he was a Democrat and/or because he was half-black? He did not get my vote since I did not believe he had the necessary qualifications.
