It is wrong for the state to control a woman's body. That is true whether it happens in one state or in all 50 states.
A majority of republican senators have signed a letter demanding Roe v. Wade be overturned. Of the latest 2 supreme court appointments, both have made rulings that suggest they might rule against access to abortion.
Even if we don't get a complete "abortion is illegal" law and/or ruling by the supreme court, the likely direction is a series of laws/rulings that keep abortion
technically legal but impossible to get. (e.g. laws that set unnecessary requirements on clinics that provide abortion that ends up causing most of them to be closed down.)
Saying "abortion is legal, you just have to drive hundreds of miles to a clinic in another city, arrange to stay out of town for several days, and can only do so before you actually know you're pregnant" is the direction that the U.S. will be headed.
And that is why the Democrats have to win, to prevent any more supreme court nominations that will allow that to happen. And that is why the "Bernie or Bust" people deserve scorn, because they are willing to let that happen.
