Rgr Shuckins... I think you're onto it. At least it sounds the most reasonable to me.
The debates will be interesting.... like no other debate ('cept for maybe the 1st televised debate). At least to me - I wasn't even alive for Nixon/Kennedy.
Because it will kind of answer the question for once and for all:
Has Bush's entire career of coming off as a dumb-arse been a calculated ploy to create such an air of low expectations as to completely disarm his opponents?
Will his performance in his final act be a continuation of that play?
Or....
Knowing that his use for that character is no longer needed, and further, will be astonishing to almost everyone if it were suddenly discarded, drop it, and floor Kerry with a performance that will stun just about everyone... ensuring another win, and justifying the use of that character for the last 4-8 years?
Or...
Will his "tick" be manifested so thoroughly that he is, despite having an actual hidden intelligence much greater than its expression, stuck?
It'll be fascinating...
