I'm still a SD resident, as is my husband. I lived there for 9 years and can tell you that SD is a pretty staunch anti-abortion state.
As we were driving up there for the first time, we passed a number of anti-abortion billboards along I-90. Most of them had pictures of angelic looking babies on there, reminiscent of the gerber baby, and there were slogans like "I deserve a chance to live" and "please don't kill me". My husband looked at me and said "I guess we don't have to guess what their stance on abortion is, huh?".
I'll be very surprised if this gets nixed.
