I'm curious to know how you actually obtained the data file from each county. Did you send letters? Emails? Make phone calls? Some combination of the above? And about how much time did it take? And did most counties charge you, or no?
The reason I ask is because we had to do this for about 120 counties nationwide for the presidential results by CD project, and it was a long, arduous and sometimes expensive project, so I'm wondering how your effort compared. It took myself and a colleague almost two months to collect all of them, and it involved a lot of emails (many unanswered), many phone calls (often more than one to the same BoEs), some formal snail mail FOI requests, and about $300 in out-of-pocket expenses for counties which charged for the data (something which drives me endlessly nuts). And it would have cost even more but for some successful wheedling with a few really outrageous counties.
We had to deal with a number of counties in NY. Most were easy to deal with, and a few charged us. The NYC BoE was pretty helpful but wouldn't release preliminary data to us for parts of Queens in which there was a pending state Senate recount, so we had to cool our heels. The worst was Nassau, which promised me a disk for ages, and then finally sent me a hardcopy canvass book.
Oh, and that's another thing. The quality of the data varied widely. Sometimes we got nice Excel files. Other times we got computer-generated PDFs. Other times we got scanned-in PDFs (ugh). And still others, we had things faxed to us (worst by far). We uploaded everything we got here:
