Here’s the most shocking illustration of the GOP’s Supreme Court problem: in the 19 years between Roe v. Wade and Planned Parenthood v. Casey, Republicans lost only one presidential race. The Court that decided Casey in 1992 included two Bush I appointees (Clarence Thomas and David Souter) and four Reagan appointees (William Rehnquist, Antonin Scalia, Sandra Day O’Connor, and Kennedy), in addition to a Ford appointee (John Paul Stevens) and a Nixon appointee (Harry Blackmun). Only one justice had been appointed by a Democrat, and that was Byron White, who’d dissented from Roe and supported overturning it.
And yet the Court upheld a constitutional right to abortion, though Roe’s seven-vote consensus for such a right was whittled down to five and several restrictions were also upheld. Three of the justices who helped keep Roe alive were consistent liberals during their time on the Court despite having been appointed by Republicans.
