...these are people actively interested in politics; they take the trouble to go to these things and I would bet every name is vetted beforehand and the candidates briefed. Obama may have met the woman asking the question (the Culinary worker) at an earlier event or before this one. Also, CNN was picking the questioners. I'm not saying there was not any planning, fixing; they ALL want positive numbers to come from it, but it is nowhere near as bad as what the Shrub did on the campaign trail. He was so afraid of being asked a question he didn't want to answer, the Secret Service removed people who were not a threat to the man's life, only his version of lies he'd told.
