Just 13 GOP women have won election so far to serve in the next Congress, down from 23 this year. With a half dozen races yet to be resolved, the House GOP — the minority party next year — is all but certain to have the lowest number of women in its ranks since 1994.

That drop-off came amid a national political climate that saw female voters sharply break from Republicans. Women favored Democrats over Republicans for Congress, 59 percent to 40 percent, according to exit polls.

It has set off a debate within the Republican Party about how to address this crisis, both in terms of appealing to female voters and recruiting and retaining women in Congress.

“I think the Republicans have to get off of defense on this issue,” Rep. Liz Cheney (R-Wyo.) said Friday in an interview.
