On the bright side, depending on how that demographically breaks down, some sections of "white women" are extremely responsive on economic issues where Obama holds a clear advantage.
It's still too early to make any broad pronouncements, but the polls seem to have come out of the Republican convention even. If the bounce just got them even, I'm reasonably happy, but, honestly, we just need to take some time to see how the polling bears out.
Afterthought: The sample size on "white women" inside the ABC Poll is likely pretty small, so don't make too much out of this unless we see it broadly confirmed.
Plus, I don't know the numbers, but, if he did really pick up +20 among "white women" to get to these numbers, doesn't that mean he probably didn't really gain in any other group? And if so, isn't one group easier to target than across the board?
Again, it may be statistical noise. Wait a week.
