All due respect, I disagree.
I don't think he campaigns as a (group) candidate. I think he campaigns as a blank slate as he promotes divisiveness and fear. He's always counted on imbeciles filling in the blanks. "I HOPE, but that other guy eats babies!" And it still works.
He's also NOT on the defensive, and people ARE buying it. Unless Romney goes on the attack to call this all out, we're screwed. I'm afraid you're off on this one. Have you seen the RNC lineup? Cold War old men desperately clinging to their power and relevance, shaking their fists and screaming at tea partiers, "get off my lawn" Too many establishment GOP sleepwalking. Obama isn't on defense.
