The New York Times article from which I lifted the chart emphasizes the magnitude of the gulf between the parties.
This article says the disparity reflects a lack of Republican women in lower offices, especially state legislatures. But why?
My political intuition tells me that women's priorities -- supports for families and children, for expanded educational opportunities, for equal pay for equal work -- fit more comfortably with Democratic orthodoxies than with the priorities of the GOP. But that seems too simple an explanation. The category of women is not monolithic. Certainly there are plenty of assertive conservative women (even if I think they are bonkers.) You would think they'd be demanding more places in the limelight.
