“I don’t think it changes much on the ground in terms of the 2018 election," Cox, the director of research at the Public Religion Research Institute, told The Hill editor-in-chief Bob Cusack on Hill.TV's "What America's Thinking."

“We found that half of women think Trump should be impeached, so there’s a lot of built-in animosity against Trump from women," he continued, referring to a poll conducted last year that found 47 percent of women said the president should be impeached and removed from office.

The survey also reported that more than 6 in 10 women had a negative view of Trump.

"Simply selecting a woman is not going to change much of that," Cox said.

Cox's comments come as Trump moves toward naming a justice to replace retiring Justice Anthony Kennedy, and speculation has swirled around appellate Judge Amy Coney Barret.

Conservatives have rallied around Coney Barret, hoping that her gender will make it difficult for critics to depict her as extreme on women’s rights and health care.
