Oregonians provide a lesson for South Dakota?

Jeff Mapes has a fascinating piece on the likely possibility of South Dakota's abortion ban being overturned. Mapes notes that the OCA's similar attempts to ban abortion in Oregon were trounced in 1990, even in hardcore conservative regions of Oregon.

In fact, the OCA's measure failed to win a single county.

I'm also interested in the fallout for conservative Republicans on this when it comes election time. Will this be something that South Dakota progressives can run on?
