According to a release from his campaign, McConnell will be joined by his wife, former Secretary of Labor Elaine Chao, and women "from across the Commonwealth" in Louisville to unveil endorsements from women in all 120 counties in Kentucky.

It's McConnell's first overt effort to reach out to female voters, a crucial bloc that Democrat Alison Lundergan Grimes is hoping to woo in her bid to defeat the Senate minority leader.

Democrats believe they can hammer McConnell on women's issues, citing in particular his vote against the Violence Against Women Act.

Indeed, Grimes' spokeswoman Charly Norton said in an email to The Hill that McConnell's record on women's issues is "shameful."

"Senator McConnell's refusal to stand up for women on key issues of economic security is shameful. From voting against the Paycheck Fairness Act and the Lilly Ledbetter Fair Pay Act, to blocking the Violence Against Women Act, McConnell has failed to lead on issues important to women and their families. Kentuckians know there is one candidate on their side: Alison Lundergan Grimes," she said.

McConnell — aware of the potential difficulty he faces with female voters — has moved to soften his image, making particular use of his wife as a surrogate. He's appeared on the campaign trail with her, and earlier this year featured her in a campaign ad decrying attacks from "far-left special interests."
