Wow, it's worth noting LaFollette has survived 2010 and 2014 Republican waves in Wisconsin and has usually won by more than 5 points. This time it turns out Tammy Baldwin did better than him, and straight-ticket voting has all the statewide offices within a few points of each other. Jay Schroeder was a joke candidate, so basically, anyone with an R next to their name can get at least 44-45% of the vote in Wisconsin, the extra 2-3% for Schroeder here I will attribute to Walker and his "coattails" if you want to say that.
Yikes, I didn't realize his last 3 reelections had been so close. I assumed he always cruised by.
