The map, which was developed by DemLabs LLC, divides the U.S. into congressional districts, showing which candidates have included women's rights issues in their platforms. Those who have received endorsements from pro-choice groups have been listed with an asterisk beside their profile, such as Democratic candidate Beto O'Rourke, who is running to represent Texas in the U.S. Senate. Gardner said the organization wanted to specifically highlight pro-choice candidates in light of growing concerns around women's reproductive rights in the U.S. "It's a fundamental issue," she said, adding that her organization felt it was important for women in particular to "be able to identify candidates that are pro-choice" and "have as much information as possible before they vote." Gardner said the organization specifically aims to mobilize "the Rising American Electorate,"  including people of color, millennials and unmarried women. Single women are one of the fastest-growing demographic groups in the country, Gardner said. The organization's map was created in conjunction with #VoteProChoice, a group representing voters who have committed to electing representatives who have vowed to protect women's reproductive rights.
