The best part is his reaction to it.....sure, his speech was pretty good, but this interview here
he is quoted saying:
"In some ways, this controversy has actually shaken me up a little bit and gotten me back into remembering that the odds of me getting elected have always been lower than some of the other conventional candidates,"
To me, it sounds like he's almost playing the race card - I'm sure numerous other people will think the same thing. It's like he's saying "I know that it wasn't right for the pastor to say that, but because I'm black I can't do anything because the white folk hold me down!"
