Isn't that exactly how the President characterized it, a last chance? Now I think that was one more mistake on his part (and perhaps he didn't really mean it since Gates has talked differently since) but then if Vitter or Giuliani or anyone takes the same position they're just following the President and to criticize them for it is therefore to criticize the President.
Has Bush given a timetable of the end of the summer? Vitter has.
