0bama will say a lot of, "Let me be clear", "I reject that notion", and a lot of stammering and uhhhs.
Based on my observations and some of what I have heard on the Glenn Beck show, whenever 0bama speaks clearly and without hesitation, he believes what he is saying, when he stammers and struggles to speak he is saying things he doesn't believe but wants you to think he does. When he says let me be clear or I reject that notion, he is flat out lying.
