The biggest problem with that "Trump template" is that it also requires lousy turnout in certain locales across the state, especially a lot of college towns. Basically it's completely unusable against anyone but Hillary Clinton. And probably not by someone who was already woefully unpopular in parts of outstate Minnesota, ravaged it with some policies and is now a former banking lobbyist.
I think it goes without saying that Tim Walz is not Hillary Clinton, and neither is Rebecca Otto, who last won this:
I didn't notice this before, but how did Otto manage to win in places like Anoka and Chisago but lose in Olmsted? It's as if she flipped their partisan orientations back to where they were in the 90s.
