Fair redistricting: California

[cvparty]

Mm, I dunno if that makes sense. Eastern Idaho has a very distinct identity--it's much more Mormon and in a lot of ways is sort of an extension of the Wasatch Range, with a bunch of small cities throughout. The Panhandle is the least Mormon part of the state and is more closely linked to Western Montana and Eastern Washington. And they are completely unreachable without traveling through Boise. Any map which links the two is an unconscionable gerrymander.

is this really an accurate accusation? who politically does it rig elections in favor of? you have to consider the limitations created by 1) the number of districts and 2) the borders/bounds of the state

Well, I'd argue that a non-contiguous district is a gerrymander, even without partisan impact.

Only Ada County is split north of the interstate highway

[Since I'm the mad scientist proclaimed by myself]

Pretty close to the current districts. A little cleaner. Both are obviously safe R.

[Dr. MB]

R+15 and R+23. Ada County is split, but this map has high geographical contiguity.

my map keeps the whole Boise metro area together

Without Boise county there's no way to get from northern to eastern ID. The mountains are as uncrossable as the Chesapeake Bay in MD without a bridge. It has the same problem as my map B.

One of the interesting things to observe here is the types of maps that Atlas produces and how they are judged. The actual map was done by a neutral group. It splits the Boise metro because the northern panhandle doesn't care much for eastern ID and they'd rather be grouped with Nampa and the Boise metro.

mm, idaho is such a remote and geographically large and nonsensical state that having 2 districts will necessarily result in some sort of incongruity...if you have one district based around Boise, at least it can be construed as Boise vs. the rest of the state/the rural wilds

Mm, I dunno if that makes sense. Eastern Idaho has a very distinct identity--it's much more Mormon and in a lot of ways is sort of an extension of the Wasatch Range, with a bunch of small cities throughout. The Panhandle is the least Mormon part of the state and is more closely linked to Western Montana and Eastern Washington. And they are completely unreachable without traveling through Boise. Any map which links the two is an unconscionable gerrymander.

The only link not through Boise city ( Ada county ) is through Boise county just northwest of Ada. It's a good highway, equivalent to most of the mountain highways. I drove it during my nine day visit to central ID last year.

The problem with the northern panhandle is it is less than half the population of a CD, and as Sol notes politically more attune with Spokane and the Flathead region of MT. Linking it to either Nampa or Idaho Falls is incongruous, but inevitable given the pop. If neutral metrics cause it to link to the east with a connection, then forcing it to Nampa can also be seen as a gerrymander. That's why I drew two plans to different neutral metrics, presumably neither can be accused of being a gerrymander.

There is a direct interstate route between Idaho Falls and Couer d'Alene that is only 27% further than a direct (air) distance, and that completely avoids the Boise area.

This is the ideal map.  since Nevada is basically a 50-50 state (1 senator from each party, only went D by about 2 or 3 points in 2016, state legislature frequently changes hands) it makes sense to have a 2R-2D split of the state.  While on average Nevada might have a 2 point democratic advantage, that is not enough to justify a 3D-1R split of the state, a 2R-2D split is very fair for a state that is about the most competitive in the nation.  with this map it appears there is a safe r, lean r, safe d, and lean d seat.  Probably a 2R-2D split except in wave election years when you could get a 3D-1R or 3R-1D split.

Some comments on OR to get things going. There are two multi county UCCs. The Portland UCC (Multnomah, Washington, Clackamas) has the population for 2.14 CDs. The Salem UCC (Marion, Polk) has the population of 0.51 CDs.

Transportation across the Cascades is limited. The following counties have connecting highways that cross the mountains. Most plans only use the first and last on this list, but the others could be considered.
Multnomah-Hood River: I-84/US-30
Clackamas-Hood River: OR-35
Clackamas-Wasco: US-26
Lane-Klamath: OR-58
Douglas-Klamath: OR-138
Jackson-Klamath: OR-62, OR-140, OR-66

These two don't fit the muon2 rules for a connection since they nick the corner of an intervening county without connecting to anything in that intervening county. jimrtex has considered connections like these as links.
Linn-(Jefferson)-Deschutes: US-20
Lane-(Linn)-Deschutes: OR-242

Thanks for grouping these together. If you'd like I'll work on scores over the next couple of days. I can priorize between the 4 states just completed, but I can't do them simultaneously.

I think there was someone that asked for Maryland, so I would do that first

Here are my two plans for OR.

My goal in plan A was to have the smallest sized county chops, and this plan only uses two chops: Lincoln with 19K and Wasco with 7K (the size of the chop is based on the size of the smaller piece from a partition). It keeps erosity low, but doesn't pack any CDs into the Portland UCC. The plan creates two highly competitive districts.



CD 1: (+444) D+6.6
CD 2: (-1547) R+12
CD 3: (-156) D+28
CD 4: (+743) D+0.9
CD 5: (+515) R+1.0


Plan B seeks to preserve the Portland UCC and both the pack and cover are maintained. Only Clackamas is chopped, and within it CD 3 picks up all of the city of Milwaukie and the CD 1-5 border follows school district boundaries in the county. The result is a CD 4 that includes almost the entire coast of the state. Though the districts are less competitive they still have the ideal skew of 1 for the state.



CD 1: (-1275) D+8.4
CD 2: (+2218) R+12
CD 3: (+307) D+28
CD 4: (-537) D+3.3

The second plan makes absolutely no sense.

First of all, you're putting Wasco/Sherman/Gilliam/Hood River in with the heart of the Willamette valley? That's like putting Fresno and San Francisco in a district together.

And second of all, the north coast doesn't belong with Roseburg and Eugene - it preferably would go in the first district. Also, Coos and Curry counties should definitely be in the same district.

[America Needs a 13-6 Progressive SCOTUS]

We should automatically disqualify AustralianSwingVoter from every state with 3 or more Districts, since he is constantly willing, and trying to violate fair redistricting criteria by trying to put as many County splits as possible all into the same County, and then trying to spin it off as a good thing like this:

Oregon Non-Partisan plan 2 (minimum county splits).

My second non-partisan redistricting plan for Oregon. Only one county is split.

Really dishonest.

It is just a personal choice. I respect the fact that many, like yourselves, prefer to not split counties between more than two districts. However I have a different approach I have previously outlined. I would also point out that the map you have quoted is very similar to muon's second plan.
However I most certainly agree with you that my Second Plan isn't good from a communities of interest view, and I far prefer my first plan. The second plan exists solely to prove that it is possible, but with grave shortcomings.
Also, what do you mean by "Really dishonest." in reference to my statements regarding the second plan of "minimum county splits" and "Only one county is split.". Those statements are true, and I cannot understand how I am dishonest in my making of such statements.

Here are my two plans for OR.

I don't like the second plan either, and I wholeheartedly agree that the in the second plan do not represent united communities of interest. Rather I have devised it as a theoretical, just to prove that you can only split one county. However the tradeoffs for only splitting one county are indeed large and in my opinion vastly outweigh the benefits. I submitted it solely for the purpose of showing other users that that it is indeed possible to split only one county.
