The OP has it completely backwards on multiple topics:
1. Striking down Roe was an excellent outcome. Morally, for sure, but politically too.
2. As a result of Roe being overturned, a majority of states will restrict abortions. As a result, there will be less abortions than had Roe been upheld.
3. The right will come out stronger in voting blocs as a result of Roe being overturned.
4. Most Americans and most independents favor placing restrictions against abortions.
5. The gerrymandering that took place in 2021, after the recent 2020 census, has strongly favored Republicans, and not Democrats, overall nationally.
