From just what exactly?
From being a member of any political party. It has nothing to do with a person's political leanings.
There are alot of theories about how Districts should be drawn.
Everybody has biasis on how to do it.
Outcomes matter.
Why let the unelected do it?
Why let the fascist Judges do it?
If they aren’t picking people at random, it’s political.
I grew up in Michigan and am familiar with the geography and population distribution of the state.
Rather than an “independent commission”, the state constitution should be amended to state principles of general applicability in drawing the districts for congress, the Michigan House of Representatives and the Michigan Senate.
This assumes that Michigan will lose one seat in the House after the 2020 Census, bringing its delegation to 13 seats. The current population of Michigan is about 9,962,000. This would mean that each of the 13 districts would contain slightly fewer than 770,000 residents.
1. Each county that contains 770,000 or more persons must have 1 or 2 districts that do not cross the lines of that county. Thus, Wayne County (Detroit) gets two whole districts. The remaining 260,000 people get combined with a contiguous county. Oakland County and Macomb County each get one seat, wholly contained within those counties.
2. All districts must be as compact as possible, and must follow county, city, township or ward boundaries where possible.
3. The counties over 200,000 persons in Michigan should be used to anchor districts, and may not be placed into multiple districts. Thus, Kent (Grand Rapids), Genesee (Flint), Kalamazoo (Kalamazoo), Ingham (Lansing), Ottawa (Grand Haven-Holland) and Washtenaw (Ann Arbor) must anchor districts and not be divvied up into multiple districts. Also, the Bay City/Saginaw/Midland three county area (they anchor a TV market and a regional airport) must be kept together.
4. The district containing the Upper Peninsula and the northernmost counties of the Lower Peninisula (currently a total of 33 counties, 15 of which are in the UP) must have a southern boundary which goes from Lake Michigan to Lake Huron which is as straight as possible.
The average size of a state House district is 91,000 (110 seats in the House). The average size of a state Senate district is 263,000 (38 seats). Use the same principles as above. Wayne County would get 19 seats in the House wholly within Wayne County. Counties such as Lapeer (immediately east of Genesee) and Grand Traverse (Traverse City), 150 miles north of Grand Rapids, with a population just below the 91,000 median size, would be kept together (court decisions allow a 5-10% deviation from the median, so county lines can be respected.
