If I’m guessing at why this was a unanimous opinion, with even the conservatives seeming to protect abortion rights, I’d say it’s an election-year punt: they get “SCOTUS Protects Abortion” headlines, while winking and nodding at their anti-abortion sponsors about post-election possibilities.
If so, there’s a note of hope in that: they feel vulnerable. They don’t have that Dobbs sense of impunity anymore. They’re afraid. Keep up the pressure!
