Women, unfortunately, vote with their emotions, and always vote for whomever offers them more goodies, to assuage their insecurities and their built-in craving to be provided for (before feminism, it would have been a man) and Obama knows that; hence this "julia" representation of the typical modern woman.
It was women who voted Obama in, and he's depending on that again--hence this "Julia" bait. Women also voted Clinton in. In fact, as Ann Coulter has noted, there would be no Democratic Party without women, who overwhelmingly vote for it. She is not the only female pundit to admit that one of the worst things this country ever did was to allow women to vote. She volunteered to give up her vote if other women would do the same.
