Not to mention, two of the champions of Roe (O’Conner and Ginsberg) have thrown its reasoning under the bus.

Do you have any resources on that? I find this genuinely interesting.

RBG has always been a fan of abortion rights via incorporating the privileges and immunities clause of the 14th Amendment to the states, a path blocked after the 19th century Slaughterhouse cases. Reva Siegel at Yale Law School is good to read about this.

*privileges or immunities clause, sorry (Not to confuse this with Article IV of the Constitution). And I guess RBG wants to use the equal protection clause directly.

That's rather the point of GP, but applied to QI instead of Roe.
