I think one party has fully grasped the ability to affect change regardless of who is in power in the other 2/3rds of the federal government, and the other party both does not differ drastically in their limited designs and also lacks the will to accomplish them, largely due to their reverence for institutions.
Support for abortion rights isn't even a hard and fast rule for Democrats. Part of the reason they failed to enshrine Roe was because the party is not unified on it. Very little has changed in that respect.
