I suspect that Walker is doing some serious posing on this one, cuz we've seen this routine before.
Reported in Gov. Walker dismisses penalizing school districts that raise money via referendum. (WKOW, 4/20/2017)
In 2016, all but 1 of the school referendums took place on regularly scheduled election days, and 81.5% coincided with the spring and fall general elections.
Wow, this is a really big problem, folks!
