Rection to the Bush's Bad Numbers

This blog attempts to "take down" the new poll that has Bush in the tank. Read it for yourself if you like. I didn't have the energy to read the whole thing, but at any point do they give a ballpark figure as to what they think the various approval ratings would be? I mean from what I did read, and assuming its not complete bullshit and/or completely meaningless, it seems like the thrust of their criticism is that the demographics were slightly off. OK, fine. Maybe the numbers are low by a point or two...or maybe even a few. That means all that ink was spilled and the most mileage they could possibly get out of it is that they've made a half-way decent argument for the notion that Bush's ratings are just really bad instead of absolutely fucking terrible. Color me impressed.
