Additionally, regarding left or right federal legislation: this would very likely be struck down by the same court under the reasoning that the constitution does not grant the federal government the power to regulate abortion.
Any federal legislation would have to come in the form of an ammendment.
I think, if Congress enacted a narrow federal right to an abortion – such as the right to an abortion to save the life of the mother – the current SCOTUS majority would be likely to uphold it - the right to life (including that of the mother) is arguably "deeply rooted in the nation's history" – and "life" is even explicitly mentioned in the text – and so such Congressional legislation would arguably be a legitimate exercise of the Section 5 power to enforce Section 1. Plausibly, they might even uphold a statutory federal right to an abortion to save the mother's health, since the right to health has an obvious connection to the right to life.
I don’t think they went so far as to definitely say there is no federal right to an abortion under any circumstances. I think they’ve left open the possibility that the due process right to life entails a right to an abortion when necessary to save the life of the mother (and possibly even when necessary to prevent severe long-term harm to her health-such as if continuing with the pregnancy was highly likely to cause her to go blind, for example). I could certainly see a future ruling (even by the current SCOTUS majority) upholding a federal right to an abortion in those very restrictive circumstances.
