Remember, Roe did not say "abortion should be permissible sometimes." It created out of thin air a right to elective abortion until viability, and made that the law in all 50 states. It was an aberration in the developed world both procedurally (the ECHR has consistently refused to recognize a "right" to abortion, leaving it to legislation) and substantively (few countries allow elective abortion up to viability).
Trump is taking credit for overturning Roe--a case virtually everyone who is still a Republican agrees was wrongly decided. But at the same time, he's advocating substantive abortion laws that reflect the center of public opinion: https://www.washingtonexaminer.com/news/campaigns/trump-repu....
It cannot be stressed enough, moreover, that the abortion laws Trump is advocating, which generally reflects public opinion, were impossible under Roe.
Maybe personally and up until he started to run for 2024 maybe even rhetorically. But a lot of that is because other GOP politicians wanted the issue evergreen, as a perpetual carrot to dangle in front of the social conservative electorate.
Trump's the one taking victory laps for delivering on it via the people he put on the Court, and that's not something that just happened randomly or accidentally.
