The positions above are extreme. Now I'm pro choice to begin with, but I imagine that MOST people on the right, even a lot of normally Pro Life people, think that it's not fair to deny abortions in situations as above. (Even if they do think the fetus is "somewhat" a child.)

If the Pro Choice movement starts a campaign aimed specifically at changing federal law to allow abortions in the situations above, I believe they have a fair chance of getting 60% within 1-2 election cycles.
