Sorry, but Dr. Cosby blew all credibility when he, along with Colin Powell, endorsed Obama simply because he is half-black. He threw away a lifetime of good works (and the usual measure of not-so-good works) with that one racist act.
As an old boss of mine once told me, one “Aw Crap!” will cancel out a thousand “Atta Boys!”
Obama isn’t even 1/2 black. He’s 1/2 white, 1/4 arab 1/4 african...More cracker than black. Its just the color of his skin....
