Video clips of Bush saying "stay the course" proves the lie of his now saying "we never said stay the course"

This video is incredibly damning, and brilliant. It shows clearly how Bush has jettisoned his own message on Iraq only 2 weeks before the election, and now wants us to believe that the old message of "stay the course" never existed. This is a president who refuses to admit his mistakes. He refuses to even admit what he said publicly numerous times. He doesn't learn from his mistakes because he doesn't recognize his mistakes - he simply denies them, then tries to rewrite history to prove they never even occurred. What's worse, the White House is now saying that they're not now "changing course," at the same time they're saying that they never said "stay the course." So what is the course?

Had enough?
