MIvoter: County Incumbents

Last update: 2/18/2026

I. Introduction and Purpose

This page is meant for MIvoter.org volunteers, who are interested in helping validate and curate our data about elected (incumbent) officials in Michigan.

In brief, we have posted summary spreadsheets about those officials, for a selection of counties.  We're asking for your help in reviewing, validating, and (as necessary) correcting the entries in those sheets.  (More guidelines will be forthcoming.)

II. Where We Are, and How We Got Here

We have been working for the last several months on building a list of all incumbent elected officials, across Michigan, for use in MIvoter.org.  (There's a longer description of why this is important, at the data volunteer guide.)

We've built this list by downloading and parsing the individual county election reports for November 2020 through 2025.  To date, we have 62% of those reports in our database, covering over 80% of the population of Michigan.  Most of this has been done automatically, via custom software that we wrote for this purpose.  Some, especially for counties using older or more confusing election report formats, have been parsed manually by volunteers.

Many of these counties are complete, meaning we have imported all of the data for that county.  We've also used AI to find contact information for many of the officials in those counties.  But we have more work to do, completing the remaining counties.

In the next few months, we will have a full-featured data editor to correct and update all officials in our database.  But in the meantime...

III. What We Need

For now, we'd like your help in validating, curating, and correcting the data we have so far.  We're starting with a handful of counties, published and shared (privately!) as Google sheets, listed below.

We're not asking you to validate every single row!  (Well, unless you really want to.)  Rather, start by eyeballing the county data:

County spreadsheets:

Glossary: Just FYI: a specific office is uniquely determined by the quad [org, office, district, subdist].  A unique seat in that office also needs the seatnum.

IV. Questions and Comments

For now, questions and comments should go to Ed or Charles.
