I find it very weird that PPP can come out with polls such as Colorado +6 and North Carolina +3 for Obama then release a national poll via Daily Kos with the President only leading by two.
It's also rather interesting that nearly all PPP's Daily Kos polls have shown a very close race.
Good point. I'd agree that if this is truly a 2 point race nationally as the DKos poll suggests, Obama should not be leading by those margins in Colorado and North Carolina. It'd be about a 2-3 pt race in Colorado, and Romney would be ahead by 3-4 in NC.
