The question dogs any woman who writes about politics: “Don’t you want to see the first woman elected president of the United States?” The unstated premise, always obvious, is that you are some sort of traitor to your sex if your hand isn’t itching to pull the lever for someone with the correct chromosomes. My answer has always been, “That depends upon what she believes.”

Hillary Clinton banked on the First Woman President effect from the start — an understandable gambit for someone with no substantive accomplishments and many flaws. Her sex may be the only thing she hasn’t lied about. She doubtless lulls herself to sleep at night by lovingly eyeing the cross tabs of election data showing that women are an ever increasing share of the total electorate (53 percent in 2012); that single women in particular lean hard to the Democrats (67 percent voted for Obama in 2012); and that marriage is on the decline among younger voters.

Two things will disturb her reverie. One: In the past two months, according to an ABC News/Washington Post poll, Mrs. Clinton’s support among Democratic women voters has dropped by 29 points, from 71 percent to 42 percent. Two: Carly Fiorina demonstrates what a true leader looks like.
