In the case of Roe V. Wade (1973), decided by 7-2, Abortion Rights for women was made federal law, with five of the seven votes being Republican appointments:
Harry Blackmun (Nixon)
Warren Burger (Chief Justice) (Nixon)
William Brennan (Eisenhower)
Potter Stewart (Eisenhower)
Lewis Powell (Nixon)
In Planned Parenthood V. Casey (1992), a later case on abortion, with some limits, the decision was 5-4, with all 5 in the majority being Republican appointments:
Sandra Day O’Connor (Reagan)
Anthony Kennedy (Reagan)
David Souter (HW Bush)
Harry Blackmun (Nixon)
John Paul Stevens (Ford)
All of these Republican appointed Justices were considered to be “conservatives” in their time frame, although Blackmun, Brennan, and Stevens came to be seen as “liberals’ over time, and O’Connor, Kennedy, and Souter came to be seen as “moderates”.
The definition of “conservative” has changed dramatically in the past half century, so all of the Republican Justices would be seen by right wing Republicans in 2022 as “RINOS”, Republicans In Name Only!
In 2022, in Dobbs V. Jackson’s Women Health Organization, all six Republicans voted to end abortion rights, although Chief Justice John Roberts wanted only further limitations on abortion, and therefore dissented while joining the other five Republicans.
These appointments were by two Presidents who lost the popular vote when they were elected by the Electoral College, along with Clarence Thomas appointed by George H W Bush.
Thomas and Brett Kavanaugh both had charges of sexual impropriety brought against them, while Neil Gorsuch gained a place on the Court that was meant for Barack Obama appointee Merrick Garland, and Amy Coney Barrett replaced the recently deceased Ruth Bader Ginsburg just a week before an election in which Donald Trump lost by 7 million votes to Joe Biden, who should have been allowed that appointment.
