it's mind-boggling enough that WI would vote for mister walker ...(compared to him the govs of illinois/maryland/mass are commies afaik)....but still be a safe dem-place in presidential years.
WI is not a "safe D" state in presidential years, but it sure as hell is with Trump as the Republican nominee, just like pretty much every other swing state except maybe IA.
This is what I've been trying to say this entire election. Republicans in Wisconsin, when not lowering taxes as much as mathematically possible, are about union busting and business putting the beatdown on workers. They are also deeply religious. An anti-trade, blue-collar-appealing, rude braggart who insults women and has no religious values or principles, is about as horrible a match for Wisconsin's right wing as you can possibly come up with.
