JAMES TARANTO: Landslide! It looks like Waterloo in Wisconsin for government unions. “It must be acknowledged that the pro-union left succeeded in making this campaign into a referendum on Walker. Had it not, it’s likely that turnout would have been much lower and Prosser’s margin of victory much wider, as in the primary. But they lost the referendum. With Prosser proffered as a proxy for Walker (we dare you to say that 10 times fast), the justice’s approximately 50.5% of the vote is a swing of less than 2% away from Walker, elected last November with 52.3%.”
