I do not see liberalized abortion happening in Texas, should Roe v. Wade be overturned, as it would cause the GOP majority in the Legislature to become hopelessly divided. Additionally, many Democrats are elected by predominantly Hispanic, and therefore heavily Catholic, districts. Outside of Austin and a few precincts of Dallas and Houston, white liberals, the most enthusiastic pro-aborts, are a relatively rare breed in Texas. Both parties would likely not touch the issue of liberalizing the pre-1973 abortion prohibition.
I'm notr so sure...the prior laws were wiped with the descision. They'd have to be passed again. That means that, instead of having to pass a permissive law, you'd have to pass a restrictive law, which is usually much harder. Don't forget, it is NOT 1973 any more...it has been thirty years now for many women. You can't reset to zero with these things.
As for your statements about Texas, most likely Texas would be one of those to "strike a balance...mandating parental notification, possibly banning PBA, but most certainly the rape, incest, health, life of the mother would also be preserved, if not first trimester abortion.
Once again, society has moved on quite a bit since 1973...it would be far more difficult than you think to move in the other direction.
Note also, in my scenarios, I have chosen not to mention RU-486 and other drugs. These pretty much change the entire game, if not totally finishing it.
My point is that, today, the genie is quite out of the bottle. It WILL NOT go back in without hearts and minds being individually changed.
