The state certified the election results yesterday. Here is a turnout increase map from 2016 Dem primary to 2020 Dem primary. Color shading is in 5 percent increments (lightest shade of red is 0 to -5%, then -5 to 10%, etc)
Statewide: -8.2%
Increase
Decrease
Most counties are within the 0 to -20% range, however the WOW counties jump out...
Waukesha - 20.9% increase
Ozaukee - 18.4% increase
Washington - 15.0% increase
There is a multitude of evidence from many states that black turnout is actually down from 2016 primaries, whereas white liberal and suburbanite turnout is way up, and that couldn't be more exemplified here as well (with or without COVID-19, it's plainly obvious)
Dane - 2.4% increase
Milwaukee - 21.5% decrease (only 5 counties have a larger decrease)
Dems making inroads in WOW is incredible.
