It's a D+13 sample, but the 2016 recalled vote is Clinton +1. Hmm.
Very good point. Tbf, in MN, there were many more Democrats who voted for Trump/didn't vote/voted 3rd party, but I doubt the electorate was D+13 in terms of registration. Also, do note the sample is just voters, not likely voters or registered voters
Trump promised infrastructure spending, and iron miners in northern Minnesota had visions of huge spending projects on roads and bridges that devour iron. It turns out that Trump's idea of infrastructure spending was to sweeten deals for privatization of highways to monopolistic profiteers whose big expenditures would be the installation of toll gantries on what have been freeways. That's not what the iron miners were looking for; they wanted to mine more ore to be spend on rebars for concrete roadways in construction or reconstruction.
...Put hefty tolls on existing highways, and there won't need to be any new construction because the traffic will shrivel.
