There is actually Roe v. Wade.
But the Supreme Court could overturn Roe v. Wade itself when it hears a Mississippi case this fall called "Dobbs v. Jackson Women's Health."
(That last sentence was plagiarized)
R v W is a Supreme Court decision that protects the privacy of abortion doctors to perform abortions. It did not discover a new right in the Constitution that all states have to abide by. The flimsy "right to privacy argument" doesn't hold water in the context of abortions. It's not about a woman's right to choose as much as it is a doctor's right to provide the procedure. The court shoehorned abortion into the Constitution using a concept that isn't applied equally in any other situation. If they did, then all recreational drug use would be protected.
Go read the massive number of articles written about it. Roe v. Wade was bad law pushed through the court to do what Liberals said was a good thing. The same group is now terrified of Roe v. Wade being revisited, because they know in their hearts it won't withstand further scrutiny given the abuse of the current abortion parameters allowing for late-term and post-delivery abortions/murders.
When passed, the ruling said "safe, legal and rare." Now it's "free, on-demand, and whenever I want - as often as I want."
The "slippery slope" paradigm has been on full display as a result of that ruling. It's past time to go back and see how we can fix this. Until politicians and judges grow a backbone and agree to even try, having it revert back to a state's rights issue makes the most sense.
