It's been said for a long time that the first woman President of the United States would be conservative. The stated rationale was that voters would somehow see the conservativeness as cancelling out the "natural liberalness" of a woman.
Margaret Thatcher does not dispel that somewhat hackneyed notion. Nor do the last two women Democrats in the U.S. that ran.
I would like you to please consider that we conservatives would vote for a conservative woman because she aligns with our values, not because something is "cancelling out" her woman-ness.
