trump starting off the week by saying he’d leave it to the states and arizona’s supreme court immediately answering him by outlawing abortion does paint an extremely tidy and uncomplicated picture of how, exactly, this will go, for anyone who is interesting in looking.
We can watch individual states taking it upon themselves to do individual bans. But we can also reasonably expect that we'll be seeing nationwide bans put forward by (at the very least the nuttier components of) the House GOP caucus. And that Trump would get behind them depending on his whims.
We'll leave it to the states, because that's what democracy entails.
And if you're worried about it being too much work for the states, good new, the decision was made for them 150 years ago!!
