I just spent some time analyzing the results of the latest WSJ/NBC poll, and thought a few things were worth noting.
While Obama has enjoyed a post-nomination bounce, it's more like the type of bounce you'd get from a rusty pogo stick that's been sitting in the garage for ten years. Obama now leads McCain by 6 points, 47-41, which is just a three-point swing from the previous poll. To put this in better context, the public favors a generic Democrat over a generic Republican by a much higher 51-35 spread, so Obama is underperforming and McCain is outperforming.
Obama continues to have a problem with white males -- McCain holds a 20-point lead among this group. On the other hand, Obama holds a 34-point lead among Hispanics, a group that he had trouble with during the primaries and that Bush made significant headway with in 2004. Obama also enjoys a 19-point lead among women -- perhaps that's another argument in favor of tapping Sarah Palin as a VP.
