As has become typical in an election marked by its often unpleasant surprises, I awoke to a storm of outrage on Twitter on Wednesday morning. Newt Gingrich had told Fox’s Megyn Kelly that she was “fascinated with sex” and didn’t “care about public policy.”

Mr. Gingrich unleashed this boorish attack after Ms. Kelly tried to pin him down on whether the many accusations of sexual assault against Donald J. Trump, and his own words on the matter, should disqualify him from the presidency.

That Mr. Gingrich (with whom I once hosted a television show) thought the best way to deflect attention from Mr. Trump’s awful behavior with women was to attack another woman tells you so much about the depths to which Mr. Trump has dragged the Republican Party.

It’s also a sobering harbinger of how hard it’s going to be for the party to win back Republican women, let alone appeal to new female voters in the future.
