Quinnipiac polling (for NY Times & CbS) was completed October 28th - Sunday. That means it does NOT include any reaction by those surveyed to how Obama performed on Hurricane Sandy, or positive remarks about that handling by Chris Christie (and now also Bob McDonnell of VA). The did not interview in Spanish - that might make a small difference in VA, more of a difference in FL, almost none in OH.
There would be NO response to the Romney ads and news coverage thereof of his dishonest ads on auto industry.
Poll for Detroit News went through Monday, which means it also does not include reactions to handling of Sandy. Similarly, the blowup on Romney ads was yesterday, so that is not included, nor is there any reaction to statements by heads of Chrysler and GM, which one has to think would have some impact in Michigan.
As far as I know, they do not interview in Spanish, but that would have very little impact in Michigan.
Both polls are only head to head, not including 3rd party candidates.
The likely voter screen in both probably understate some of vote for Obama.
In other words, do not hyperventilate about closeness either in MI or in FL or VA.
UPDATE PPP has Obama up WI 51-46 and IA 50-45. Key points - over 50 in both, 5 or more point lead in both.
IMHO Obama wins WI, OH, IA and NV & election is therefore over. Question is only margin on popular vote and how large EV margin will be.
