Here's a challenge for you--make all congressional dsitricts in Maryland at least 60% Obama.

MD-01 (Blue): 60%D-38%R
MD-02 (Green): 60%D-39%R
MD-03 (Purple): 60%D-39%R
MD-04 (Red): 61%D-37%R
MD-05 (Yellow): 60%D-39%R
MD-06 (Teal): 60%D-38%R
MD-07 (Grey): 61%D-37%R
MD-08 (Light Purple): 78%D-21%R

District 8 could be broken up more if the other districts needed to be strengthened.

I've been trying to gerrymander Louisiana with three majority black districts, but I figured out that it isn't quite possible with six districts without making the map completely ridiculous. However, it can be done with the current seven districts.



All less than 500 from ideal:

Blue: 85% White, 10% Black
Green: 54% Black, 43% White
Purple: 77% White, 13% Black, 5% Hispanic
Red: 74% White, 22% Black
Yellow: 50.3% Black, 46.5% White
Teal: 80% White, 15% Black
Gray: 61% Black, 31% White

Lousiana has actually had far more atrocious gerrymanders than this in the past.

Come on now, guys, if you're gonna gerrymander Louisiana, DO IT LIKE A MAN.

Behold! With 2000 census numbers, four black-majority districts:



(all districts +/- 750 from ideal)

green: 50% black, 47% white
yellow: 50% black, 47% white
teal: 50% black, 46% white
gray: 50% black, 41% white

blue: 86% white, 7% black
purple: 85% white, 12% black
red: 85% white, 9% black

It's such a horrible monstrosity of a map, I love it. I challenge anyone to beat this!

Is the red district even contiguous?

[RI]

I don't know if this has been done before or not...but here is Michigan with three black districts from 14.



I lost the totals, but the dark green, yellow (inspired by NC-08), and gray districts are all just barely over 50% black.

Could I get a zoomed in version of the one in San Jose, too? I tried recreating it, but I wound up a ways short on population with no large asian enclaves remaining and I was just hovering over 50% at that point.

Does anyone know if it's possible to make a third Asian-majority district in California, specifically by using the Asian populations near and in the San Francisco/Daly City area? I've been playing around with it, and so far I've gotten districts with about 46%/47% Asian with full population with just those areas. In another version, I took in some Asian areas in Oakland as well, and I got it up to 49% Asian. It might be possible with some finesse to make one that reaches 50%, if someone wants to give it a try, though it probably won't be pretty.

For those who have wanted to draw state leg districts or whatever for At-Large states, there is now data for every state except Alaska up.

Hooray!

Is a McCain district possible?

Yes, though barely. The Yellow district is 49.975% McCain. It may be possible to get it over 50%.
