I'm working on a Republican gerrymander of NY. So far I'm still working on New York City and Long Island. I have made NY-1 and NY-9 into two McCain districts. I hope to post maps soon.

I think you can make a 64-35% McCain district in New York City if you find the right parts.

[Shilly]

Cool. Shows just how dominant Maricopa County is in Arizona politics.

Anyway, I tried to do a Republican gerrymander but got lost because I had no idea which white areas of the Phoenix metro were uber-Republican and which were moderate to Democratic (beyond some obvious things, like Mesa being a Republican stronghold). But I imagine a map with three Democrats and seven Republicans would be feasible, with all three Democratic seats being heavily Hispanic. It might not be possible to get rid of Giffords (because there isn't much you can do in Tucson, and any fiddling with the AZ-01 border makes either Giffords or Kirkpatrick safer), but you could make it impossible for the Democrats to hold her seat without her.

If it's any help, this map of the 2008 Presidential election in Maricopa was posted in another thread. Have to give credit to realisticidealist for creating this, by the way. I'm sure it took a lot of work.

Well good thing the chance for a GOP gerrymander is basically zilch.

Oh, no. There goes my time.

[nclib]

officepark, would you mind giving a color key for the New York map.

[RIP Robert H Bork]

officepark, would you mind giving a color key for the New York map.

That's pretty hard, because it's not like I can think of a name for each of the 28 colors. Alright, I'll try.... (by the way, I numbered the districts according to the color key that the program always uses, so for example district 1 is always blue, and the district 1 in the map is blue too).

[Хahar 🤔]

My precinct:

Total Population: 1,873
White: 907 (48%)
Asian: 883 (47%)
Hispanic: 36 (2%)
Black: 0 (0%)
Native: 0 (0%)
Other: 47 (3%)

I just pulled up a TX map, and loaded my old file, but I didn't see the partisan data. Is there something else that I need to do?

It looks like I can get the test data, or my already created districts, but not both.

I meant and/or geographic description. Outside of NYC, they should be identifiable by county.

I was frustrated by that, too.

Also, he rejigged the California voting districts in such a way that has created a ridiculous number of non-contiguous zones, making redistricting really tough. Annoying

I noticed that "feature" in CA, too.

I've also had problems for the last month with the saved maps. When I run them with the converter, the image is criss-crossed with obscuring lines. I've tried on different machines with no difference, but if I use an old saved file things are still OK. Anyone else had this problem?

[Verily]

Yes. There appear to be tiny gaps between all of the voting districts that are impossible to fill.

[RBH]

I created a VRA-free Dem-friendly map for Texas, here are the numbers, but I need to assign all the random small precincts and this might force the alteration of some of the districts.

CD1 (Gohmert): 69/31 McCain
CD2 (Poe): 64/35 McCain
CD3 (Johnson): 60/39 McCain
CD4 (Hall): 70/29 McCain
CD5 (Hensarling): 55/44 Obama
CD6 (Barton): 65/34 McCain
CD7 (Culberson): 56/43 McCain
CD8 (Brady): 74/25 McCain
CD9 (Green): 55/44 Obama
CD10 (McCaul): 66/33 McCain
CD11 (Conaway and Neugebauer): 72/27 McCain
CD12 (Granger): 51/49 Obama
CD13 (Thornberry): 76/23 McCain
CD14 (Paul): 60/39 Obama
CD15 (Hinojosa): 62/37 Obama
CD16 (Reyes): 65/34 Obama
CD17 (Edwards): 54/45 McCain (still need to put 29K more in this district, The Chet Edwards Wilderness Preserve, 23% African-American)
CD18 (Jackson-Lee): 74/25 Obama (42% Hispanic, 32% Black)
CD19 (Marchant): 62/37 McCain
CD20 (Gonzalez): 57/42 Obama
CD21 (Smith): 65/34 McCain
CD22 (Olson): 60/39 McCain
CD23 (Rodriguez): 56/43 Obama
CD24 (open, same general location as current CD24): 51/48 Obama
CD25 (Doggett): 56/42 Obama
CD26 (open, random East Texas): 67/32 McCain
CD27 (Ortiz): 68/31 Obama
CD28 (Cuellar): 56/43 Obama
CD29 (Green): 71/28 Obama (58% Hispanic)
CD30 (Johnson): 67/32 McCain (36% African-American, 32% White, 28% Hispanic)
CD31 (Carter): 62/37 Obama (Eastern Travis and Williamson Counties for the win)
CD32 (Sessions and Burgess): 50/49 Obama
CD33 (open, San Angelo/Abilene): 69/30 McCain
CD34 (open, wrapping around Chet's district): 69/30 McCain
CD35 (open, lots of SE coastal Texas): 62/37 McCain
CD36 (open, Republican parts of Tarrant, assorted counties near DFW): 71/28 McCain

Still gotta hammer out some population problems.

Aside from getting sued, this map could always lead to Granger picking the 36th over the 12th.

But 16 Obama CDs out of 36 isn't all that bad

[Verily]

I drew a map with 15 Obama CDs out of 36, with none marginal like the version of Granger's district you have. It's also VRA-compliant. I haven't finished it yet because I need to work out how the area around Edwards's CD will be designed.

Basically, it consists of four Hispanic-majority CDs in South Texas, El Paso and stretching up the coast to parts of Corpus Christi; two Hispanic-majority CDs in metro San Antonio; two Democratic white-majority CDs in metro Austin (one Hays+SW Travis, the other NE Travis+SW Williamson); two black-plurality districts, a Hispanic-plurality district and a Hispanic-majority district in metro Houston; a black-plurality and a Hispanic-plurality district in metro Dallas; and a coalition district in metro Fort Worth. Plus Republican districts filling the surrounding space (including a district containing all of the San Antonio suburbs and completely enclosing the two San Antonio districts).

TX-01
Brownsville, Hispanic parts of Corpus Christi, coast in between
81% Hispanic, 62% Obama

TX-02
McAllen and environs
88% Hispanic, 68% Obama

TX-03
Laredo and the low-population areas of the Rio Grande Valley
86% Hispanic, 64% Obama

TX-04
El Paso and environs
76% Hispanic, 65% Obama

TX-05
SW Austin and Hays County
60% Obama

TX-06
NE Austin and SW Williamson County
61% Obama

TX-07
North San Antonio
61% Hispanic, 58% Obama

TX-08
South San Antonio
55% Hispanic, 58% Obama

TX-09
S/SW Houston and environs
38% black, 26% white, 25% Hispanic; 70% Obama

TX-10
Other black parts of Houston
43% black, 25% Hispanic, 17% white; 79% Obama

TX-11
Hispanic E Houston
60% Hispanic; 63% Obama

TX-12
Downtown Houston and environs
40% Hispanic, 38% white; 57% Obama

TX-13
SE Dallas and environs
44% black, 27% white, 27% Hispanic; 79% Obama

TX-14
W Dallas and Irving
47% Hispanic, 33% white, 14% black; 60% Obama

TX-15
SE Fort Worth, E Arlington and Grand Prairie
42% white, 26% Hispanic, 25% black; 63% Obama

The rest are McCain to various degrees, all strongly so.

[RBH]

here's the current state of the Chet Edwards Wilderness Preserve (in dark blue):



TX22 (which is actually open) is in brown (Galveston, South Harris), CD25 and CD31 split Travis in a way that there are two Obama districts coming out of Travis County. CD7 and CD29 have similar colors.

Here's the DFW map

[Bacon King]

I've spent most of the day on a Texas map, with the mission to make as many Obama districts as possible. For some reason though I only used 34 districts instead of 36 so rather than fine-tune this map I'll remake one with a good number of districts.

Regardless, the map I have now has 11 districts that are Obama+5 or more, 12 districts that are Obama+4 to +1, and 11 districts that are McCain+15 or more. 23 out of 34 Obama districts is kind of crazy, even if most of them are marginal.

[enlightened despot]

I wanted to make a map for Mississippi with two black-majority seats and ended up with this chaotic monster. The blue district is 53% black (to 43% white) and the green district is 54% black (to 43% white). Unknowingly it looks like I've moved every incumbent (other than Bennie Thompson) into a unwinnable spot, as Travis Childers is stuck in the purple district and Gene Taylor is mired in the red district. It's bad for Gregg Harper too, as he's in the blue district. Could any of those guys survive this map?

[Bacon King]

I've completed my 36 district democratic gerrymander of Texas. 23 districts are Obama+3 or better, 2 districts are tossups, and 11 are Republican.

I'll post pictures later.

The designs in Panola, Tallahatchie and Winston are quite interesting, what you have going on in Walthill might take the cake though.
