In interviews, suburban Republican women who back Jones said they did not want to face this choice. Suzanne Turner, the chair of the English Department at Calhoun Community College in Huntsville, stressed that she went to church every Sunday and helped raise money for Republican Jeff Sessions when he ran for Senate.

“I’d like to see someone in there who’d support Trump, but I believe the women” who have accused Moore, said Turner, 67. “I put a Doug Jones sign in my yard. I felt a little sick doing that. But I had to.”

The Jones campaign has stepped up its outreach to suburban women, with events such as Louise Jones’s coffee visits, designed for undecided voters. A television ad that began running last week portrays eight of Moore’s accusers and asks if voters will “make their abuser a U.S. senator.” A digital ad, also running heavily, lingers on each photo, and accuses Moore of “immoral” behavior.
