Contributions to abortion conglomerate Planned Parenthood have surpassed $20 million in the most recent midterm fundraising cycle, according to an analysis of federal election data by watchdog group OpenSecrets.

Democrats have wagered heavily on progressive backlash against the Supreme Court’s decision to overturn Roe v. Wade earlier this year as a tailwind for keeping vulnerable lawmakers in office. OpenSecrets reported that Planned Parenthood Votes, the organization’s super PAC, has raised approximately $2 million between the beginning of September and the third week of October.
