Until this morning, I have never bought into the idea that weekend polling actually is bad for Republicans -- I understand the reasoning, but regarded it as mostly anecdotal and not entirely accurate (Democrats also run errands, do things with their families, and watch football on weekends), but I have seen two things this morning that have changed my mind.
The first is this Fox Poll, which is much better for Kerry than their poll from last Thursday showing Bush leading by five points. A seven point swing in four days -- especially when most polls (including other tracking polls over the same period, along with the national polls such as Pew, CBS, Gallup, etc.) show Bush with a small but consistent 2-3 point lead -- tells me mostly that the FNC poll is reporting statistical noise or, at least equally likely, is not a representative sample.
The second and more important consideraton was a statement from Ed Geoas, one of the two Battlground pollsters and a professional political pollster.
So, now put me on the list of people who are suspicious of weekend polls. :)
I, too, haven't bought into the idea, but while I'm now a bit more suspicious, I'll rather wait until tomorrow before hopping on the bandwagon. If President wins by a comfortable margin (PV 3%+), I'll have to concede.
