If McCain can pick up only 2 points over the weekend, which is very doable, he'll be "in the sweet spot" and the undecideds will break his way to finish the job!
Over at Hedgehog, Polaris who is a statistics wizard, says that if the internals in the poll hold, Obama is “toast”.
It’s never too late until election day. Sarah Palin guaranteed McCain would in PA. I would trust her judgment on any day of the week over pollsters who tend to oversample Democrats, ignore the results of Operation Chaos, and who cannot detect when PUMA’s and union members of PA are blatantly lying to them. And pollsters who are in the tank for Obama just skew the results even more.
