"Stay the course"was never part of it. (That will teach you dirty, damn, liberal hippies to stop taking those hallucinogenic drugs and dreaming up phrases to try to put into Bush's mouth.)
From Think Progress:
STEPHANOPOULOS: James Baker says that he’s looking for something between “cut and run” and “stay the course.”See! Bush has NEVER been “stay the course."
BUSH: Well, hey, listen, we’ve never been “stay the course,” George. We have
been — we will complete the mission, we will do our job, and help achieve the goal, but we’re constantly adjusting to tactics. Constantly.
So just stop it!
He never said that!
