Nate Silver does the knowledge:
What's interesting, however, is that while there is a gender gap in these numbers, it's not the one many observers were anticipating. Rather, along a variety of metrics, men like the Palin choice better than women:
These numbers pretty much speak for themselves, but men have a favorable imperssion of Palin by a 35-point margin, whereas women have a favorable impression of her by an 18-point margin. Conversely, by a 23-point margin, women do not think Palin is ready to be President, whereas Palin lost this question among men by a considerably smaller 6-point magrin.
Why does this gap exist? Don't know, but it may simply be a matter of ideology. Men are generally a bit more conservative than women, and opinions of Palin are very strongly determined by ideology.
I have to say that I'm not surprised that women are harder on Palin than men---she's repping for them, after all. But moreover, I'd be utterly surprised if there weren't an "insult factor" at work here. More to the point, I bet there's a strong possibility that a portion of Hillary voters will actually be repelled by the pick of Palin. I'd be very interested to see how these numbers broke down by age, for instance. The more I think about this, the more ite appears that the upside here is in locking down the evangelicals. I don't know what else there could be. It's not like McCain needed help with men, or working class whites.
