While I don't think the decision will be overturned, I do think abortion rights need to be on sturdier legal ground so that they can be better protected across the board. Roe v. Wade was decided largely on grounds regarding the right to privacy (and a doctor's right to practice medicine, included in their own right to privacy), which doesn't really get to the heart of the issue. A stronger legal standing could possibly help combat the wave of anti-choice laws we're seeing in a lot of states.
But, hey, I'm not a legal scholar! So I could be wrong.
