MADISON, Ala. — The Democratic nominee for U.S. Senate in Alabama has begun to use Republicans’ words against them.

The latest ad by Doug Jones plays back criticism of Republican nominee Roy Moore that Ivanka Trump, Attorney General Jeff Sessions and Sen. Richard C. Shelby (R-Ala.) gave in the aftermath of allegations that Moore made unwanted advances on young girls.

In the ad, now in heavy rotation, President Trump’s daughter is quoted saying “there’s a special place in hell for people who prey on children.” Sessions is quoted from a congressional hearing where he was asked about the Moore story: “I have no reason to doubt these young women.” Shelby, who has been critical of Moore, is quoted on his plan to write in another name.

With three weeks until the special Senate election, there’s little evidence that Moore will follow Republicans’ advice and quit. His persistence has left Republicans, who once hoped to drive him out and run a more electable write-in candidate, out on a limb.
