Yeah, I was thinking that maybe I missed something.
Kavanaugh even addressed the issue in his concurring opinion, that there's nothing to prevent women from traveling out of state for an abortion and it's not even "especially difficult as a constitutional matter" he made a point to stress.
Any state that tries to pass laws preventing women from traveling out of state for abortions will, at the very least, not have Kavanaugh on board, and probably none of the eight other justices.
