On Jan. 25, hundreds of thousands of abortion opponents assembled in Washington, D.C., for the March for Life. The weather was freezing, but they’re used to that. Roe v. Wade, the Supreme Court case that declared abortion a constitutional right, was decided in January 1973. Every year, pro-lifers hold the march to mark Roe’s anniversary and renew their commitment to overturning it. “It might be 20 degrees out here,” activist Ryan Bomberger told the crowd, “but it has not put out this fire.”
