I disagree completely. The Clintons are calculated down to the very words out of their mouths, fingers pointing, and facial expressions.
Obama has gotten by on good speechifying and appeal to the left wingers for so long that he was able to ramble on and on in the past without damaging himself. Now that he is on stage trying to pull in middle voters and traditional blue collar and small town dems, it is becoming more noticeable how many speaking gaffes he makes. The kool-ade drinkers don’t care because of his Messiah act. In the past, he’s just been able to ramble on and on without consequence.
