Ahem, using the numbers you provided, Newsweek has Bush up +11 % the first week of September, while for the same week Gallup has Bush up only by +2%. You call that agreement?
See the my post #102 above, its an article by the pollster Zogby, it explains why Newsweek as well as Gallup and some others, vary all over the place from week to week.
Ahem, ahem. Go back and read my post again.
I NEVER made any claims about about the percentages these polls moved to reach their Sept numbers.
My statement was that Newsweek, Gallop, ABC, Time (and CBS it turns out) ALL showed Bush with a solid lead in Sept.
And the numbers I posted show exactly that.
