Didn't PPP have a poll out in late September with both Obama and Carmona up in Arizona? Or was that some other pollster? In any case, every pollster will have some outliers.
I'll remain skeptical for now.
That poll came during Obama's post-DNC mega bump. He was up nationally and up by around 9 in Ohio and Virginia.
Carminative was pretty competitive in the fall. He got the amount of support in the final results as in his poll numbers. The undecideds were just GOPers and they broke in a big way for Flake.
