After the 9/11 attacks Bush had unmitigated support. However BEFORE the 9/11 attacks in no way whatsoever did Bush have the press behind him. The honeymoon period ended about 2 years after the attacks.

The question is what would have the press done, not what would Bush had done. If this happens in 2006, 7 or 8 then in no way does the press treat Bush like they are treating Obama now. With the exception of Fox, the press has supported Obama without question or investigation. This presists.
