I think painting Obama as the "angry black male" is the right-wing version of the so-called "race card".Remember, we got eight years of Boy George Bush thanks to the fear factor. They are hoping to make it work again.
Matt Drudge on his blog put a picture up of Michelle Obama kissing Joe Biden, and Barack kissing Jill Biden. What's the message there? They want you to fear interracial relations. They are playing on that century old notion that blacks shouldn't be with whites.
