After decades of tiny steps and endless setbacks, America’s anti-abortion movement is poised for the possibility of a massive leap. With the Supreme Court due to deliver a landmark ruling expected to seriously curtail or completely overturn the constitutional right to abortion found in the 49-year-old Roe v. Wade decision, anti-abortion advocates across the U.S. are hopeful they’ll be recording a win.

They say their work will continue even if Roe falls.
