It’s not just La Crosse. I remember a few years back when Finegold won. The paper showed a map of all the areas that voted for him and they were only towns with a UW campus. The rest of Wisconsin, the working class and farmers, largely voted against him.
The universities with their leftist professors and ignorant students are a solid voting bloc for the left.
That is what happens in Minnesota too. Universities are hotbeds for out-of-control leftists.
