Does it matter? Americans oppose overturning Roe by 2-to-1 and that's not going to stop the Court.
And leafing from there, logically speaking, the Court can't not overturn Obergefell, or all of the rest of them, because they all rely on the same 14th Amendment due process right-to-privacy argument Roe does. I don't see how that 14th Amendment can apply to some of them but not to some of the others.
And good luck getting a permanent national right-to-abortion, right-to-marry-who-you-want, or any other similar-type law through Congress, since even if they could get enough legislators on board to pass it, it would surely be struck down by this or a similar court on 10th Amendment grounds.
