I’m not seeing the narrative on Democrats trusting SCOTUS here, Roe was decided in 1973 under the Ford administration. The next Democrat president Jimmy Carter was highly christian & saw only to uphold the law despite disagreeing with it & only viewed expect in the life of the mother. Congress from the 70s-90s still depended on Southern Democrats for any Democratic majority & they were very much opposed to supporting Roe. Even as you get to Bill Clinton he later loses congress to a Republican majority.
Best cases were first term Democratic presidents Clinton & Obama who were both in no position to swing for the fences on large issues that would split their own party(Untested in Obama’s time) & who would both see Republicans sweep majorities in congress at re-election time . We are only at this level of support due to hard work of Democrats over the years to rebuild after losing southern voters but it comes at great risk of losing the Senate. Clinton & Obama use to be able to count Ohio & Florida as blue states.
The game of getting consensus & then even winning a legislative victory is tough out there.
