Remember that time people were called hacks for saying this was a Leans D race back in July/August? I do!
Honestly, they still would be. This is Toss-up at best. Marquette has been hugely wrong before (President Hillary Clinton says hi). Walker is a tough campaigner and is seen as a generational hero in the Milwaukee suburbs (the apparent kind of places Dems focus on to the detriment of the rurals).
Now that college-educated whites are shifting away from the Republican Party, I can see the WOW counties voting for Walker by lesser margins than they did in 2010, 2012, and 2014 for Walker.
