They may be aware of an issue with the polling.
What I have observed - in the polling, decisions and the pattern in Europe is, that people are willing and amenable to a middle ground.
Say, ending them at 18 weeks. Considering that the majority are ended by 12, that's extremely reasonable, and in line with nations that allow it. I've observed before, there's but a few countries on Earth that are as liberal as WE are regarding abortion.
I've mentioned before - we have one side's extreme that wants it banned, period, no exceptions at any and all times, and even with the moral religious view, that's medically unacceptable. We have the other extreme view that has actually claimed that a fetus does not become a "person" (and thus endowed with rights) until it LEAVES THE HOSPITAL - making it legally ok and not infanticide to abort a child AFTER IT IS BORN.
A middle ground can be accepted and voters are open to it. It's already been achieved in Europe.
