Why don’t Republican women run the way Democrats do?

Slowly but inevitably, the two major political parties have become the party of women and the party of men — guess which is which — so that the 2018 midterms are shaping up as a climactic battle in the war between the sexes.

This is largely the Trump Effect — his attitude and remarks toward and about women — as well as the recent Supreme Court confirmation hearings for Brett M. Kavanaugh.

Democrats were already woman-ing the barricades after Donald Trump defeated Hillary Clinton in 2016. But the Kavanaugh kerfuffle fired up Republicans — men and women — as well.

Republican men, on the whole, were appalled by Kavanaugh’s treatment and are expected to express themselves accordingly at the polls. Republican suburban women, who generally still don’t like Trump, nonetheless welcomed the FBI investigation requested by Sen. Jeff Flake (R-Ariz.). Largely satisfied with the results, they’re back on board to vote against Democrats. In other words, thanks in part to Flake, voter intensity on the right has more or less balanced the intensity on the left.
