As the Idaho redistricting commission moves deeper into its mission on its second day, a quick shot – here – at a legislative redistricting plan, with the idea of isolating where the stress points and idiosyncrasies may be.
Stapilus legislative plan (1)
The map as developed is available at the Idaho Maptitude site under the user stapiluscarlton, as “My Current Legislative fast.” The latter referred to my intent of doing it quickly, with an eye to keeping the deviations between district size as small as possible, but political considerations (such as legislator residences) to a minimum. It started from the current districts, and held to population equality as a main principle, along with keeping counties and cities and general communities intact where possible.
The norm in Idaho remapping is to start from the north and working south, since the panhandle districts are more dictated by the narrow geography. Here, I followed a piece of advice offered Tuesday morning, to start both there and in the southeast – another mostly lightly-populated area – working toward the big Ada-Canyon population center, where shifting lines would be most easily accomplished. The other advantage, and the one specific district bias I had in drawing it, was to eliminate the ungainly district at the southeast corner of the state running from Preston to north of Driggs, often through country without a highway serving the widely scattered communities. It is the poorest district in the state at present, and I simply concluded the people there shouldn’t have to put up with it for another decade.
The end result is not perfect (there are a number of small oddly-assigned areas, which don’t change the bigger picture but were hard to remove). But the highest deviation for any district was 4.7%, pretty low, and most were much lower than that. It probably could pass legal muster. (I think.)
Here are a few things that became clear in the process of drafting it.
Lewiston and Moscow always have been united in their own separate districts, and anchored them. That may simply not be possible this time. This map splits Lewiston, and it may be hard to redistricters to avoid doing something like that. That’s just the nature of the population shifts.
The long-running big district in the east, long anchored at the southeast by Rigby and running off to Salmon and Challis, would logically this time be split up. A district tossing Lemhi and Custer counties in with Blaine would make redistricting sense – and a real pot boiler of a district.
Because the current Democratic/competitive districts of Ada County (16, 17, 18, 19) lie toward the middle of a large population area, many outcomes are possible. But absent heavily political maneuvering, this seems most likely: One district (19) with an ongoing Democratic advantage, and the other three with infusions from precincts which have had strong Republican advantages. Of the three districts, 16 (or a rough equivalent) seems most likely to give Democrats some advantage, and 18 least.Share on Facebook
