Republican Gerrymander of New York

by: Alizarin

Thu Feb 10, 2011 at 9:53 PM EST


This diary presents a theoretical Republican gerrymander of New York (27 representatives) that should, in the normal course of events, yield a 16D-11R delegation. Exactly how Republican a seat needs to be to be safe is a matter for debate, but in none of the projected Republican seats did Obama receive more than 47% of the vote which I feel should be safe most of the time. This map make makes quite a bit of use of water contiguity both around Long Island and Lake Ontario, however there is no touch point contiguity. Population deviations are all less than 1000 (within 0.15%).

Districts are numbered in reverse order to the current system, low numbered districts are upstate and high numbered are downstate.

NY-1 (Blue): More or less similar to the current 28th including the most Democratic parts of Buffalo, Niagara Falls, and the western Democratic parts of Rochester. Uses water contiguity on Lake Ontario instead of following the coastline which helps to push the PVI a little more Democratic. O 71% M 27%  
NY-2 (Green): Reasonably similar to the current 26th in that it includes parts of the Buffalo and Rochester suburbs and the areas in between. O 47% M 51%  
NY-3 (Dark Magenta): At this point upstate New York starts to take departures from reality and no longer resembles the current districts. The western parts of the southern tier, the south Buffalo suburbs, and wraps around Rochester to take in the eastern suburbs.  O 47% M 52%  

NY-4 (Red): Eastern and southern democratic leaning areas of Rochester, water contiguity to Oswego and a thin strip to metro Syracuse, tendrils to both Utica and Ithaca. O 64% M 35%  

NY-5 (Gold): The remainder of the southern tier, the territory between Syracuse (including its western suburbs) and Rochester, wraps around to southern Syracuse avoiding Ithaca. O 47% M 51%  

NY-6 (Teal): Northern Syracuse, northern Utica, Rome, north along the Lake Ontario coastline before turning east and then south, terminating short of Albany. O 47% M 52%  

NY-7 (Dark Grey): The Democratic leaning northernmost counties, a narrow strip running down the eastern state line, Saratoga Springs, Schenectady, and Albany. O 62% M 36%  

NY-8 (Slate Blue): Otsego County centred, with arms running off in every direction sucking in Republican leaning districts. O 47% M 51%

NY-9 (Cyan): Both the east and west state lines with convoluted lines grabbing the most Republican parts of Rockford County O 46% M 52%  

NY-10 (Deep Pink): Binghampton, Middletown, Peekskill, Newburgh, Poughkeepsie, Kingston, and the land connecting them. O 60% M 39%  

NY-11 (Chartreuse): The Democratic parts of Rockland and parts of Westchester, down the Hudson river coastline a little. O 66% M 33%

NY-12 (Cornflower Blue): More of Democratic Westchester, including New Rochelle and Mount Vernon, plus some of the northern Bronx. O 85% M 14%  

NY-13 (Dark Salmon): Southern Bronx, much like the current 16th. O 93% M 7%  

NY-14 (Olive): Northern Manhattan, much like the current 15th. O 92% M 7%  

NY-15 (Dark Orange): Southern Manhattan. O 82% M 17%  

NY-16 (Lime): Little bits of Kings, Queens, the Bronx, and Manhattan. O 79% M 20%  

NY-17 (Dark Slate Blue): Mostly Queens. O 81% M 19%

NY-18 (Yellow): North-eastern Kings. O 95% M 5%  

NY-19 (Yellow Green): North-western Kings and the northern shore of Staten Island. O 90% M 9%

NY-20 (Pink): South-western Kings and Staten Island minus its north shore. O 47% M 53%

NY-21 (Maroon): South Eastern Kings, and connected by water contiguity, the entire south coast of Long Island from Long Beach to Montauk.
O 46% M 53%

NY-22 (Sienna): Mostly Queens. O 71% M 29%

NY-23 (Aquamarine): Horrendously tortuous district picking up everything republican in southern Westchester, Bronx County, Queens, and Nassau and using repeated water contiguity over Eastchester Bay and the Long Island Sound to do it. O 47% M 52%

NY-24 (Indigo): Republican areas north of Jamaica bay in Queens, as well as southern Nassau, and a little south-western Suffolk.  O 47% M 52%

NY-25 (Pale Violet Red): The most Democratic parts of central and southern Queens and Nassau. O 90% M 10%

NY-26 (Grey): The republican parts of Eastern Long Island O 47% M 53%

NY-27 (Spring Green): The Democratic parts of Eastern long island, in four sections, each connected by water contiguity along the Long Island Sound. O 63% M 37%

Nice..
Would probably take over Maryland as the most hideous gerrymander in the nation if it were to happen.

I also smell a hint of dummymander in off years for the Republicans.

Eh, 47% Obama is something like R+6, that's pretty efficient. Especially in Upstate where local strength is higher than the Presidential numbers suggest


[ Parent ]
Dems came close to winning NY-26 in 2006
it smacks very strongly of dummymander in another Dem wave.

Wow...
Long Island is a sight to see in this configuration..... :o

Ad hoc, ad loc and quid pro quo!
So little time, so much to know!


95-5
I'm impressed by that 95% Obama district. That got me to thinking: what's the most heavily Obama district possible to draw in the US? Gotta be in an urban center: Chicago, LA, New York, maybe even San Francisco+Berkeley+Oakland

We already have one
http://en.wikipedia.org/wiki/N...

I doubt it could get more Dem than this...

No, it's definitely possible
Obama got 97% of the vote in the city of Detroit, for example. Depending on how you dealt with the enclave city of Hamtrack and Highland Park and also the Grosse Pointes, it could probably even be relatively compact and pretty-looking.

I looked over California is Dave's App. I'm reasonably sure that it's not possible to draw 95% plus Obama districts in either the Bay area or the LA area. Neither have sufficient African American population, which is what you really need to draw the most pro-Obama district possible. I'd look at Chicago, Detroit, Philadelphia and Baltimore as the most likely places to be able to draw the most pro-Obama district.

Maryland didn't pan out but Pennsylvania did
I tried both Prince Georges and Baltimore based configuration in Dave's App. Both topped out at about 92% Obama.

I did get a 97% Obama district in Philadelphia, though. If I had been more careful about which precincts I choose at the end, I may have been able to keep it at 98%, but I'm not sure.

Detroit.
This was the most Democratic district I was able to create in Detroit.

90% Black District - Detroit

It's 90% Black, 5% White, 3% Asian and 1% "Other." The only area outside of Wayne here is Royal Oak Township in Oakland County, which is 94-96% Black.

For those not from Michigan, here's a map of Detroit's racial composition. If your not familiar with Dave's coloring scheme, blue is AA, red white, green Hispanic.

3% Hispanic, not Asian.
It's less then 1% Asian.

you could prob. draw a fairly compact ...
97-98 Obama one in Chicago (?);   NY too above 95 (one exists at 95 !) ; i don't think in any part of CA (?) though maybe if it was very gerrymandered

[ Parent ]
Actually
I wasn't trying at all to maximise that district at all but I got that part of Kings to 98% Obama quite easily. McCain only got 3779 votes...



[ Parent ]
That'd be like...
Being the only 8 people in all of King County in Texas out of 159 voters to vote for Obama (and that was 93% McCain, less partisan then the district you created above).

If Democrats wanted to create a district like this for Republicans, how high of a McCain district could you create out of New York City?

I think about 65% without leaving the city.

With significant
gerrymandering I could create a R+21 PVI district like this

That's good for about the 13th most Republican in the country.


[ Parent ]
Not all NYC
A goodly portion of the population appears to be in Nassau county.  

[ Parent ]
True
Teach me for not knowing the area (or checking!)

This is almost exactly the same partisan breakdown.

99% Obama
It took some effort, but I just had to see if I could make a 99% Obama district:



[ Parent ]
A work of art
Personally, I've gotten Democrats to about 23/27 safe seats in NY. It's pretty remarkable how much control you can have when you draw the lines.  

That's quite stunning
It maximizes all those Republican pockets of strength scattered about in NYC and Long Island very well.

VRA
How's this do with VRA? Looks like the South Bronx, Northern Manhattan, and Brooklyn VRA (at least I'm assuming they are) districts are all intact, and even 53% black current NY-06 looks to be ok, though who knows about the added parts of Nassau.

Great job though! I especially love your NY-23!

Well
The racial breakdown for districts that are white minority are

       White     Black     Hispanic     Asian
12th     23        36          34             3
13th     7         30          58             2
14th     23        28          44             3
16th     47         8          30            11
17th     24        13          46            14
18th      8        75          12             2
19th     27        36          25             8
22nd     33        10          24            26
25th     14        58          16             5

This means the are two White plurality (but minority) districts, like now. One Hispanic majority and two Hispanic plurality districts, again like now. This map has two Black majority and two Black plurality districts whilst the current map has three black majority and zero black plurality districts. A court might well find that to be retrogression, or maybe not really. Either way it wouldn't be very difficult to change (and hardly the biggest problem they'd have with this map).

Contiguity issues
Even allowing for liberal water contiguity, your 23rd and 27th can't be contiguous without a touch-point:

Without a touch-point, your 27th necessarily requires a longitudinal cut of the Sound (that is, follow it lengthwise as opposed to cutting across it), from Manhasset to Bayville and then on to Suffolk County [the green lines].  However, connecting the Westchester part of the 23rd with the Nassau/Suffolk parts requires a cut across the Sound from Rye to Glen Cove, which will necessarily need to cross the 27th [the orange line].


A touch-point in the water?
That's my signature!  

[ Parent ]
(Actually, it doesn't need a touch-point)
But. . .

[ Parent ]
Hrmm
Good point! I'm going to call it a feature, "16D-11R Gerrymander of New York - Now with Aquatic Touch-Points!"

fascinating study
Yup the GOP actually did control redistricting in 1972-the last time a party had complete control in NY.  Seems like a long time ago.

I personally deplore wild redistricting maps.  Most of the % or two gains are not worth it.

I personally think we will see fewer wild maps this year.


It could end up like this
The GOP does have an ace in the deck. The Chief Judge of the Federal appellate court is GOP appointee and if it goes to that court he would be the one to appoint the Judges who would hear the case. So the Dem's had better settle with the GOP in the legislature. We forget that angle.

Not, it really couldn't
If it goes to the courts, they'll appoint a special master, who will draw a reasonable-looking map. It won't be this spindly-looking mass of GOP spaghetti.

There isn't a court in the country
that would implement a map anything like this.

Phantom concern.
