I think the tendency to blame McCain for his own campaign woes is largely misplaced. Its the record of GWB and the larger GOP that is more to blame for McCain's tanking poll numbers.
The chickens of eight years of bad governance are all coming home to roost at the worst possible time for McCain. Maybe some future good news external events will help stop the bleeding for McCain,
but sadly, for McCain, on a cause and effect basis, most of all new news will probably benefit the democrats.
I might as well blow my own horn because no one else will, but I said way back in July and earlier, McCain had to take firm control of the GOP and kick GWB to the curb after he had the nomination wrapped up, McCain did not, and now he appears doomed. And now that the economy is tanking, McCain has no real remaining reformer credibility because he straddled the GWB fence too long. And when it comes to the economy, it was a McCain open mouth, insert foot, for McCain to say, the economy is not my area of expertise. Especially when McCain's economic advisers are lobbyists and Phil mental recession Gramm and Obama has a blue ribbon panel real economic experts.
