If there wasn't a record, you might think that Obama was heading for a major upset victory in PA next week. Zogby has Obama just one point behind Clinton at 45%-44%.

But remember, Zogby was out in front this year predicting Obama's big wins in California and Ohio too. So it's hard for me to put too much weight in this sounding.

That said, I always try to remind myself to watch the actual numbers, especially when the polls are slipping out of sync with conventional wisdom. And the last four polls released have Clinton's lead at 1 (Zogby), -3 (PPP), 6 (Franklin and Marshall) and 5 (LAT/Blooomberg).
