I’ve always felt it should be federally legal, but much of the country doesn’t so not possible now and state laws are a protection. Congress could do things to make it legal but really it’s up to the Supreme Court and not much power there.
Throughout history implementing power to the states has been a stepping stone towards nationwide laws. We could see a time when the government decides to make abortion illegal across the country. In the event that happens, power to the states is a good thing until the majority sentiment shifts towards making it federally legal again.
If a billionaire supports it, it’s not good for you. Unless you’re a billionaire. Maybe a millionaire.
