It’s not a popularity thing, it’s a constitutional thing. If the founders thought popularity was #1, their would be no need for a constitution besides a national vote.
Plus, the same popularity and statism you are promoting for this specific argument, is an exact argument for abortion as a national right.
Its not 50% of states, it’s called state elections. All abortions were illegal in most of them before your statist vision made it a national right.
What made abortion legal was your anti social conservative Supreme Court.
I’m still amazed that you see infanticide, (or partial birth abortion) as a state right.
