2020 Census and Redistricting Thread: Washington

[Former President tack50]

Here is a mild Dem Gerrymander. This map basically does 3 things:

1: Shore up the 8th district while not harming any of the current other Dem districts
2: Turn the 3rd district into a true swing district
3: The 5th becomes marginally more Dem, but probably not enough to matter

All while mostly (but not fully) trying to keep COIs intact and what not. Not sure to what extent gerrymandering is possible tbh.

I am sure you can be a lot more agressive, probably making the 3rd into a Dem district and not a tossup and possibly making the 5th into a tossup or even a Dem district. On paper the numbers are certainly there for 9-1, though you probably need snakes into Seattle to do it?

How connected are Pierce and Yakima though? IIRC there's a pass there but it probably makes more sense to cross the Cascades in the North or South.

Actually indeed it turns out they are not connected by road (there is a pass but the roads force you into other counties shortly after it anyways).

That can easily be solved by crossing the Cascades further south on Lewis County instead of Pierce (so the 4th takes the eastern 2/3 of Lewis County and the 10th takes the portion in Pierce), and has no real effects on partisanship.

My attempt at a fair map

In theory this map should work as a fairly standard 7-3 map, with districts 2 and 3 being swingy but still clearly benefiting one side over the other. Districts 6 and 10 might flip if there is both a scandal and a big R wave but they are unlikely to do so.

Finally district 9 (coverin Seattle) is a Dem landslide that borders on comical
