 But conservatives argued since then that Roe needs to be overturned. Our Constitution, the 9th and 10th Amendments, first of all, the Constitution doesn't mention abortion at all. Therefore, it's not the purview of the federal government. The 9th and 10th Amendment are unambiguous that any powers not vested in the federal government are reserved by the states and the people. This means that the issue stops being a federal one. Once Roe is overturned, it goes back to the states. You could have 50 different abortion laws.
