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 Democratic 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. It's almost inconceivable that the Roe effect alone is insufficient to account for Justice David Prosser's victory.
Editor: I have trouble with double negatives. I think this means he's saying the Roe effect is enough to account for Judge Prosser's victory.
