Yes, I agree - those conservatives definitely took it too far abolishing Roe. :):):
Roe was not a legislative act, but a Supreme Court ruling. The Republican party did not abolish Roe v Wade, or abortion, for that matter. For that to have happened, the Republican Party would have had to have a super majority in the Senate (that would have consisted of 60 republican senators who were all supportive of an abortion ban) or, if they did not have a super majority , enough Democrats to join them in passing a Constitutional Amendment stripping away the federal protections of abortion. They never had a super majority, a caucus that was willing to support an abortion ban, or democrats willing to support such a ban.
What happened was 6 Supreme Court Justices found that Roe was a flawed ruling without constitutional merit. It was the Supreme Court correcting one of its prior rulings; it was not a political party abolishing a law.
Another thing to consider when analyzing the effect of abortion on American politics: you have often posted that the Repubs will not win any elections until they abandon their pro-life stance, but what you are not factoring in is the voters they'll lose if they abandon their pro-life stance.
According to a pew poll I saw during the 2020 election cycle, 30% of pro-lifers said they would never vote for someone who isn't pro-life, while less than 20% of pro-choicers said they would never vote for someone who isn't pro-choice. So, if that poll is anywhere near accurate, repubs stand to lose many more votes than they'd gain by abandoning their pro-life stance.
In other words, for your prediction of Repubs never winning another election to bear out, the repubs would actually have to do exactly what you say: take a pro-abortion stance. If they want to win (something they did in 2022, BY THE WAY, as they won the House of Reps), they must do exactly the opposite of what you say.
