"More voters than not say that Barack Obama would benefit from picking a female running mate, while the opposite is true for McCain, according to a new poll by the Lifetime Network.

If Obama chooses a woman as the Democratic vice presidential nominee, 29 percent of female voters said they'd be more likely to support him and 15 percent said they'd be less likely. If McCain picks a female running mate, 15 percent of women voters said they'd more likely to back him and 20 percent said they'd be less likely."

That's from the Hill site.
