Sen. Barack Obama could have shown real independence and criticized Hillary Clinton for her race-baiting remark about Republicans — she said the House of Reps is run like a “plantation” — but instead he lamely decided to defend her. I’m not saying he needed to denounce her; he could have very gently said that some metaphors simply aren’t appropriate and that although he’s sure HRC meant no harm, we need to be careful about what we say. But he didn’t. By the way, if you want to see a good example of photo bias, see the picture that accompanies the story.
