Here's a early contender for Most Convincing Post by Kalabus.
Obama has none of the stereotypes whites like to attribute to blacks, he isn't a loose cannon, he's paced, respectful, calm, speaks well in their eyes.....all those sort of things that don't scare old white people. He did have periods where he got a "little cocky" to many white people I know, when he seemed to shrug everything off and not get rattled, a little too sure of himself, and that fed into a stereotype, but that has seemed to have subsided.
Obama gets this as well, and tries as hard as he can to avoid race. If anyone found a single incendiary remark from him, angry at America in any way? He would be hurting.
When his wife was talking about election history and said this was the first time in her adult like she was proud to be an American, everyone clutched their chest and as they scrambled to quanitify their indignity about having their nation potentially questioned when it came to greatness, all the pundits could oddly yell back though is "She went to the best schools and she isn't proud of her country?" which I found baffling and confusing, I have no idea what that has to do with being proud of a nation's actions, even though she wasn't talking about that.
He has to highlight that "only in America" story because white people want to believe that, want to believe that America is more generous and accepting than the rest of the world (bold faced lie, but who's keeping track?), he can show no signs of bitterness about America, can't make any white people feel any guilt over how non-white protestants have been treated in American history and how that still impacts today.
I think he gets all this from having grown up around white people and being able to see the sort of insecurities in people that need to constantly be reaffirmed that "America is best!" over and over.
