[New_Conservative]

How are you guys getting the election results per congressional district?

How are you guys getting the election results per congressional district?

The box at the top. You can see city names, lines, county names, lines, population, election results (2008), CD labels, etc.

How are you guys getting the election results per congressional district?

Daves Redistricting App used to make the maps can bring up population by 2010 precinct for most states. They will have 2008 presidential results for those precincts, and they get added as the district is drawn. DRA also has other elections from the 2000's for many states.

Alabama:



82.2% Obama
17.5% McCain

District is 70.7% black. Rest of the state was 68.3% McCain, 30.8% Obama

Texas:



The red district is 84.3% Obama, 15.7% McCain. It's 41.8% black, 39.7% hispanic, and 15.7% non-hispanic white. Rest of the state was 57.0% McCain, 43.0% Obama.

For an added bonus, the district right next to it is a 66.2% Obama district, contained entirely within Tarrant County.

I found that a district entirely in Brooklyn can exceed 97% Obama, but I don't think NY can match the 99% in IL.

[Mr. Illini]

If you use Obama '08 you can break 98% staying entirely within Chicago. The hometown effect was BIG. Going just a little to the south I was able to reach 99% Obama for a CD sized for 2010. One can go higher using 2000-sized IL CDs. Even so, the rest of the state was still 59.2% Obama.

Incredible.

I found that a district entirely in Brooklyn can exceed 97% Obama, but I don't think NY can match the 99% in IL.

I wonder if you might actually do better in Harlem and the South Bronx.  Don't have the patience to hunt and peck through individual precincts, though; and pretty sure you're right that 99% isn't happening.

79% Obama

Cool map

[ElectionsGuy]

56.4% Obama in Utah. McCain won the rest of the state with 70.2%. I wonder if Mitt Romney carried this district. Its probably likely that he did, although narrowly.

[Adam Griffin]

Obama 84.2%
Dem 81.7%
White VAP 66.0%

Rest of WA: Obama 54.2%

Michigan:



97.2% Obama, 2.4% McCain. Rest of state: 54.6% Obama, 43.7% McCain.

Mississippi:



69.7% Obama. 29.7% McCain. Rest of state: 65.5% McCain, 33.6% Obama.

Tennessee:



81.5% Obama, 17.9% McCain. Rest of state: 61.8% McCain, 36.9% Obama.

Kentucky:



62.0% Obama, 36.9% McCain. Rest of state: 61.7% McCain, 36.8% Obama. Pretty pathetic, I'm sure bandit can do better than this.

Ohio:


83-16 Obama

Rest of the state: 49.4-49 Obama

I'd try to get a bigger margin, but I'm no expert on the racial demographics of the city.  Also, it slowed my computer down a lot.

[Bandit3 the Worker]

62.0% Obama, 36.9% McCain. Rest of state: 61.7% McCain, 36.8% Obama. Pretty pathetic, I'm sure bandit can do better than this.

I had one that was similar except that it avoided downtown Frankfort, ran along the edges of rural counties, and stretched all the way up to Dayton in northern Kentucky. Still it was over 60% for Obama.

[The world will shine with light in our nightmare]

76-23 Obama

Rest of the state: 59-40 McCain

[The world will shine with light in our nightmare]

Arkansas - No county splitting



54-44 Obama

Rest of the state: 64-33 McCain

[The world will shine with light in our nightmare]

Kansas

60-38 Obama

Rest of the state: 62-36 McCain

Nebraska

57-42 Obama

Rest of the state: 64-35 McCain

New Hampshire:



59.6-39.6 Obama. The other district would go 50.2-49.0 McCain.

Connecticut:



There was so much blue and so much population within precincts, so I wish I could've gotten more into it, but I tried to get the most Obama areas and got 77.1-22.0 Obama. Rest of state is still pretty solidly Obama at 57.7-41.1

Oregon:



Now, I don't have election results here, but this is my guess as to the most democratic district, probably going ~75% Obama.

[ElectionsGuy]

Idaho:



52.4% McCain, 45.3% Obama. Rest of state: 71.1% McCain, 26.4% Obama.

Hawaii:



With the rest of the state shaded in. Went 74.7% Obama, 23.5% McCain. Rest of state (rest of the island, really) went 68.6% Obama, 30.1% McCain. Not much wiggle room in Hawaii because its so consistently ~70% Obama.

[ElectionsGuy]

Arizona:



71.0% Obama, 27.7% McCain. Rest of state = 55.5% McCain, 43.3% Obama. Who knows what this would've gone in 2012. Remember than inner city Phoenix (AZ-7 and the part I have shaded) swung hugely to Obama in 2012, more than any other district in the country actually.

Virginia:



79.8% Obama, 19.6% McCain. The current VA-3 was 79.0% Obama in 2012, 78.5% Obama in 2008, so it was quite a challenge to exceed it, but I did it.

Rest of state = 50.1% Obama, 49.0% McCain

Florida:



89.4% Obama, 10.6% McCain. Not too much more democratic than the current FL-27 that went 86.2% Obama in 2008, 87.5% Obama in 2012. The rest of the state went 50.2% Obama, 49.8% McCain.

These numbers are without third parties, but it still doesn't make much of a difference. You only really have to take off .5% on average (but lower for the district I created) to get more accurate results.

Iowa:



64.8% Obama, 33.6% McCain. You really can't get any real high numbers in Iowa for either side. This is basically a strip through Des Moines, Cedar Rapids, Iowa City, Davenport, Dubuque, and Waterloo. Rest of state went 50.4% Obama, 47.9% McCain.

Maine:



63-36 Obama

Rest of the state: 52-45

[The world will shine with light in our nightmare]

Indiana:



72-27 Obama

Rest of the state: 52-47 McCain

[The world will shine with light in our nightmare]

New Jersey:



84-16 Obama

Rest of the state: 55-45 Obama

There's probably a way to get to >90% Obama in this area, but I don't know how the black vote is patterned here.

New York:



I managed to get 96.7% in NYC outside of the Bronx. The current NY-15 went 96.7% Obama in 2012 (and its in the Bronx). But remember that NYC swung towards Obama in 2012, so this district would probably be north of 97% in 2012. Rest of state still went 62-37 Obama.

Pennsylvania:



96.3% Obama. Rest of state = 52-47 Obama.

Indiana:



Sorry Scott, this one's 77-22 Obama.

Here's a map of these:

[politicallefty]

Before it crashed on me, I had a relatively compact district in Los Angeles County. It would've been the most Democratic district in California, exceeding even the Bay Area district I made before. It was about 96% Obama (and about 95% Brown). I think it was something like 51% Hispanic, 46% Black, and just over 1% White in terms of VAP. There wasn't a single precinct in the district where Obama had less than 90% of the vote.
