NC really looks out of reach, and it is NC after all. He won NC by 0.4% against an RCP ave of ).4% for McCain, and swing of 0.8%.
See the table for 2008 State/LastRCP/Actual/Diff
CO 8.5 5.5 3
FL 2.5 1.8 0.7
IA 9.3 15.3 -6 Bradly effect
MI 16.5 13.5 3
NV 12.4 6.5 5.9
NH 9.5 10.6 -1.1
OH 4 2.5 1.5
PA 10.4 7.3 3.1
VA 6.3 4.4 1.9
WI 13.9 11 2.9
I have always said I have to see IA to believe it, the whitest state in the union. Similarly, NV has shown actuals that blow away the thin polling (and see Reid 2010 on that as well). The effective ground same in PA, WI, OH, VA, MI and CO are all well documented. McCain generally over-polled everywhere where there was state polling (with some variation and some going the other way) this generally being attributed to high dem turnout vs rep.
The spin in the ground game has only improved in VA, OH, FL.
D has increased registration vs R in all but NH and CO (of 7 swings).
D has increased early voting in all but NV (of 4 swings).
D has increased absentee requests in all but OH (of 4 swings).
Everything in OH is a guess as they do not register by party, affiliation is assigned by House district winner.
IA could easily surprise to red.
I expect NV to go blue along with the NV senate seat. NV massively under-polls blue. Don't know why.
