NARAL Pro-Choice America hosted a call on Sunday night discussing threats to Roe v. Wade from a conservative-tilted Supreme Court, during which ten thousand activists participated. Indivisible, a resistance organization formed at the onset of Trump’s administration, put out a guide encouraging constituents to confront Senators about the upcoming vote. And Protect Our Care, devoted to preserving the Affordable Care Act, launched an ad highlighting the potential of a new justice who would vote to overturn pre-existing conditions.

And that is only the beginning, as activists say they’ll employ similar strategies of office visits, protests and advertisements that ignited constituents in protest last summer during the height of the Republican congress’ ACA repeal efforts.
