I think you identified it well. This is along the lines of my own personal philosophy: always tell the truth. You know why? Because I don’t have all that great a memory, so it’s real easy when you tell the truth all the time...you don’t have to remember all those sordid, useless details surrounding a lie. Could this be why McCain is so quick with answers and Obama stutters?
I think this is a big part of the stammering, stuttering, glazed-over eyes; I honestly think he is thinking, “oh, crap, what did I say about this last time? hmm...what would sound about right, what sounds good this time? hmm...”
He probably cannot keep his stories straight and frankly cannot remember all the tales he’s spun.
Has anyone ever asked him: tell us in detail exactly what you did as a “community organizer.” Who signed your paycheck, what was your daily routine? I have not heard anyone ever ask him this.
