These probably all decently underestimate Trump in the same way that in 2018, FOX Polls decently underestimated Braun, Hawley, and Cramer.
Or a unpopular president is in serious trouble and f losing a state he won by less than 1%

Trump was at 48% approval with Wisconsin's 2018 electorate. Given that Trump supporters will have even higher turnout in a Presidential year, it's very easy to picture Trump at over 50% in Wisconsin.
I'd expect Trump's support in the rurals to be even higher AND his support in the WOW suburbs to be higher as well, relative to 2016.
And remember...Hagedorn beat Neubauer despite them trying really hard to take him down.
All in all, things are looking pretty rosy for Trump. In the same way that you can look at old 2016 polls and scoff, you can look at these old polls and laugh at how so many of them massively underestimated his final numbers.
LOL, no. What makes you think that Trump will somehow improve in Milwaukee suburbs while collapsing in other suburbs across America? Man, the obsession with WI being lean R in this election is getting tiring!
