Marquette had Clinton+6 in the 2nd November 2016. Let's all remember. Second of all, this may be good news for the Dems, but the legislature won't flip if all the gains are concentrated in Milwaukee and Dane counties. This means that if Walker loses and wins a revenge 2022 matchup, we'll be back to a GOP trifecta in no time. Stay watchful, Wisconsin Dems. Don't get complacent and keep fighting.
Actually, Democrats have a reasonable shot at flipping the state Senate this year, especially considering that they've won 2 state Senate seats already that voted heavily for Trump.
Also, are you forgetting that a Governor Evers would prevent Republicans from drawing fresh gerrymanders in 2021 even if they still controlled the legislature? If Evers wins this time, Wisconsin's legislature will probably be up for grabs for most/all of the 2020s.
