Well in general election polling, Obama still fares better than Hillary does in polls at the moment on average. So if OBAMA is not electable, that must mean...
...but in the broader sense, her saying "he cannot win" in the heated conversations she had with Richardson before the Obama endorsement is really an indirect reference to the Wright controversy.
She, and everyone else, knows this shit WILL be brought up in force in the general election. Whether or not this is gonna kill Obama yet is unknown... I admit I have my own worries about how serious it will be in the long term.
But in the short term, he has certainly weathered that storm.
