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%
