No, not a post about how the Wisconsin Supreme Court might rule on an abortion case, but vice versa: how abortions have affected the Wisconsin Supreme Court.
Here are some Badger State numbers: Roe v. Wade legalized abortion nationwide in 1973. The Wisconsin Department of Health has statewide figures on the annual number of abortions going back to 1975. Tot up the numbers through 1992, and you come up with 316,457.
Scott Walker won the governorship last year by a margin of 124,638. That may not be within the margin of abortion; after all, some of the missing 316,457 would have voted Republican had they existed, and many would not have voted.
But JoAnne Kloppenburg, the left-liberal state Supreme Court candidate who was supposed to save Wisconsin's labor monopolies from Walker's reforms, lost by just 7,316 votes, according to the Milwaukee Journal Sentinel (this figure is pending a possible futile recount). It's almost inconceivable that the Roe effect alone is insufficient to account for Justice David Prosser's victory.
I.e., if abortion had not been legalized by SCOTUS in 1973 there would have been many more leftist adults to vote for Kloppenburg in 2011. Extrapolate to other leftist causes as desired.
