Should have information at your county's website
The MN Dept of Administration site has a contact us page for the commissioner.

To find the commissioners for a specific county, you can also visit that county's official website. For example, Hennepin County has a page where you can find your commissioner by district. Similarly, Yellow Medicine County has a page dedicated to their commissioners.
Kick in to the DU tip jar?
This week we're running a special pop-up mini fund drive. From Monday through Friday we're going ad-free for all registered members, and we're asking you to kick in to the DU tip jar to support the site and keep us financially healthy.
As a bonus, making a contribution will allow you to leave kudos for another DU member, and at the end of the week we'll recognize the DUers who you think make this community great.
