Obama uses Palin to connect with the people. LOL he can’t relate to him on his life.
Also I believe he suffers from an adult form of ADHD and often loses focus and concentration unless he is able to kep himself tightly disciplined. When confronted with a stressful situation he loses focus says dumb or incoherent things and stumbles into trite phrases like"let's not play games" as a substitute for discourse.
