Obama is NOT an “African-American” nor does he share anything in his upbringing or life experience with urban black Americans.
I tried to point that out to people before he was elected. He was using what happened to be the color of his skin to get ahead. Something he has done his whole life. And he did this on the backs of people like MLK and others who have a right to bitch about what happened to their ancestors*. Obama does not because as you so rightly pointed out he has no connection to the decendents of slaves. Other than his fathers ancestors selling them or his mother's buying them.
How smart can a guy be when he cannot do the most simple thing a politician can do. And that is give a speech. Obama looks like he is watching a tennis match when he reads the teleprompter. Never trust a man who cannot look at you!
If people want to compare Obama to Palin let's start by comparing her birth certificate and school scores.
