As a former Minnesotan who doesn't pay very close attention to the state's politics (but much more than a state to which I have no ties), it's my understanding that everything good Walz did, it's because voters and organizers pushed good bills into the legislature for him to sign. He also did bad things.
The lesson: push him and Harris, and no need for hero worship.
(Tho I too am happy it's not Shapiro)
