And how widely known (really) is Amy's maltreatment of her staff? Minnesota was actually competitive for Donald Trump in 2016 while Klobuchar was being re-elected by a 24% margin, roughly 22% of whom were also voting for Trump.
I hope you are right, but ignorance in the down ticket races is severe.
I should add the 24% re-election margin for Am Klobuchar was 2018, not 2016. So not exactly the same pool of voters, but many of the same pool nevertheless.
