Seriously though, there is no sign that Wisconsin is still a Democratic-leaning state at the presidential level. A Tossup? Yes. But lean or likely D? No. Trump was an awful fit for the state and still won it, and it was basically tied in 2000 and 2004 as well. Ron Johnson decisively won a race that he was never supposed to win, especially in a presidential year.
Pre-election polls showed Kasich winning the state in a landslide against Clinton, Cruz and Rubio also led in most polls, IIRC.
I agree with this, except for the "especially in a presidential year" part. What is with this Obama-era assumption that "presidential years" are inherently more Democratic?
