I made this map assuming New York will lose one seat, all incumbents will win in 2010 and Republicans will hold NY-23. I chose to assume Republicans would hold the 23rd district because it seemed easier to redistrict out the 23rd district than the 26th.

With slow population growth and redistricting out the 23rd district, districts had to move East and North. Since I started in the West and making it more Democratic Hall’s district changed a lot but Dutchess and Putnam Counties account for over 50% of the district which are in his district now.

The numbers for the 23rd and 26th are not exact numbers because I could not find political data for Steuben County so I split up the numbers based on population. I would assume Corning is less repulbican than Steuben County on a whole, but since I dont know the area and couldnt find information on it I just split Steuben up evenly.
The 23rd picks up more of the Rochester exurbs and loses its strong republican areas in the Southwest. Monroe County now makes up about half of the district.

After his close call in 2008 making Arcuri’s district safer was one of my main goals. Picks up the rest of Tompkins and Broome Counties making it more Democratic.

Lee would now live in the 27th but I assume he would run in the safer 26th. Becomes more republican after losing its areas in Erie County and picking up most of the heavy republican areas from the 23rd.

I kept the general earmuff shape of the district the same to allow the 23rd to pick up more of Monroe County. I also kept it pretty safe considering Slaughter would be 93 on election day 2022 most likely creating an open seat in the next decade. I also drew Slaughter out of her own district but I did it mainly to make it easier to calculate the results it wouldnt much diffrence to draw an finger out to Fairport like there is now.
I think what you really may be setting up here is Scozzafava vs. Tonko. Of course, she would find it rather hard to “run against Albany.”
I worry about Arcuri in the interim. . .
Especially on not splitting municipalities, which is hard to do. I like the creativity on John Hall’s district. I think he might appreciate that, as his new district plays we to his environmentalism and isn’t dominated by rich suburbs.
I’m working on an all Democratic Upstate that doesn’t look like a blatant gerrymander. It splits Buffalo in 2. I’ve shortened the Hinchey district’s “finger” but I’d like to get rid of it, and I appreciate the way you did it.
Not to do with the redistricting itself, but, as a matter of curiosity, would it be possible for the rep for number 21 [Albany] to drive from one end of his district to the other in winter time?
