Exactly, it should be up to the states.
I would vote against a pro-abortion polician.
That's the way it should be.
It's too easy to manipulate the result when you are going through a referendum. If Republicans are smart, they need to amend their state constitutions now to get rid of it. Otherwise, the Democrats will start to use it often as their "loophole".
Well, laws and policies on abortion, are being enacted through the states. With Roe vs. Wade overturned, liberal states are enacting liberal abortion laws. Some more conservative states have stricter abortion laws.
Things are happening state by state, though not always going in the pro-life direction. Not even all conservatives want absolute bans on abortion. Which is why we see states enacting laws banning abortion after a certain number of weeks, and/or with exceptions for rape and incest and life of the mother.
