In the seemingly never-ending march toward the total resignation of the entire administration, Alberto Gonzales has resigned from his post as Attorney General. In my opinion, Mr. Gonzales had, like Rumsfeld before him, been a buffer between the public and the vice-president, a sort of whipping boy, who took the blame for what were clearly the vice-president or president's bad decisions.
To me this seems like paving the way for Bush's own resignation. Think about it: the replacements have never been the old cronies who would risk all for their President. They are politicians themselves, and won't go down willingly for Bush.
It's certainly a start.
