The type of women who would be turned off by the reportage on Santorum aren’t Republicans. But that’s also why most women aren’t Republicans. Most women are brainwashed into some degree of feminism at the colleges. And since they’re better students than men, the liberal brainwashing seems to stick in their heads more than it does men’s.
That’s certainly part of it. Another is that women tend to feel rather than think. Appealing to feelings is part of the liberal ploy. Feelings can be manipulated.
