I think people have forgotten how dangerous the Clintons were and why this board exists. It does not help that poppy Bush is rehabing the Clinton's image.
I wonder if this has more to do with Bush Sr. trying to stay in the news. George W. seems to be his own man and Daddy might not like being out of the limelight. By paling around with Bill, he gets recognition and perhaps sends a message to his son of some disapproval - is there a family rift? It is unseemly to me.
