The auto unions and teacher's union are a key constituency in each of these midwestern states. When you go against either, like Corker went against Union President Littlefield, and the way Rauner has gone against Karyn Lewis, GOPers like Walker are making a big mistake and won't win.
Meh. Republicans have been seen as anti-union for many, many decades, and they used to fair much better in those states - at a time when union membership was significantly higher, too. I doubt that's the tipping of the scale.
