Roe v. Wade.
The decision was a solid majority of 7 to 2. The composition of the vote is fascinating. Fully half of the Republican majority was from Nixon appointees and two from Ike. FDR and LBJ got one each. Dissenters were from both parties, one from JFK and another from Nixon.
What you had was a court led by six justices put there by Republican presidents that lost one vote but gained two Democrats. In essence, the Nixon-Eisenhower Republicans joined the FDR/LBJ minority.
So, when someone yells and screams about abortion, remind them four Republicans and three Democrats decided the vote.
Ike putting a Democrat on the court is priceless but then that same Democrat went on to lead the Liberal wing and served for 34 years. You go Ike!
