Sounds to me like the middle ground is allowing abortion. You don't have to have an abortion. If you want one you can, in the n first weeks of pregnancy.
That's the middle ground.
Maybe the far-left should wake up and ask for mandatory abortions up to carrying term for every woman so that the far-right finally understand that "allowing abortion" is already a middle ground.
It's funny how when one side is reasonable and the other is not, the middle ground must lean towards the unreasonable one.
