Planned Parenthood’s political action committee will devote $20 million to mobilize voters across the country for the 2018 midterm elections, the group announced Wednesday.

The women’s health and abortion provider group’s PAC, called Planned Parenthood Votes, said that the campaign would be the largest ground game effort ever for a midterm. It will target states that include Arizona, Minnesota, Georgia, Florida, Michigan, Ohio, Wisconsin, and Pennsylvania.
