Roe was 7-2 back in 1973.
The court had 4 judges willing to overturn it at the time before Byron White's death, Casey v. Planned Barrenhood. Renquist and White were the two original Roe dissenters and they were joined in Casey by Scalia and Thomas
But I see what you mean: Ginsberg ultra-liberal (er, mainstream) replaced White, almost a conservative.
Yup. She tipped it 5-4 to 6-3.
Yeah, but 2 years before that, didn't Thomas replace the raving lunatic Thurgood Marshall? Even today's Stevens doesn't compare to the ridiculous activists from the 60s courts.
