Working together?
Leftists don't compromise with anyone. They simply infiltrate and subvert the system. It is what they are best at. Really, it's all they know.
It is their way or the highway, which is why abortion is being deregulated all across the country via state, even in Red states via state constitutions. They present their amendments as returning to Roe vs. Wade, when in actuality, there is no verbiage to restrain abortions in the third trimester, it is all a big lie to completely deregulate abortion. Now it will all be done in secret.
The extremists have quietly taken over after Roe was overturned. They have zero incentive now to compromise with anyone about anything. It was the only way they could have done it. Like you said, over 2/3 of the populace are opposed to late term abortion, and would never have voted for it, so quietly legalizing it was the only way they could have gotten away with this crap. But Leftists, being Leftists, are full of shit, so there is that.
