So you believe that most people who voted for McCain knew fully well what his policies were? That they knew they were going to be implemented, and would work?
If you voted for Dubya (and now it seems like no one wants to admit they ever did), did you feel you knew his policies? Did he come close to succeeding?
McCain was sunk before he ever began, given the albatross that was the last 8 years with a Republican president. His campaign just made it worse.
