There are at least two reasons he will not do this. First, even if he realizes his situation, President Bush will find it too difficult to break the habit of covering up ‘untidy’ matters, as opposed to exposing them on purpose; thus he will continue to try to give his son an ‘honorable’ escape. The second reason is fear of his wife’s abusive reaction.
If I were George H W Bush I’d probably go ahead and join the public opposition, because of the importance of this opposition and the gravity I’d be giving it.
