Long Island write-in votes, methodology

Sources, clocks, and what is not claimed
Suffolk results are the public page https://app.enhancedvoting.com/results/public/suffolk-county-ny/elections/GE2026_20261028145605. The results timestamp is November 4, 2026, 12:24:42 a.m. ET. The saved files were checked November 6, 2026, 9:55:42 p.m. ET, and the ballot-item list at November 6, 2026, 9:55:46 p.m. ET. The file says the results are not official. Nothing on this page is a count after that snapshot, and no race is called.
Nassau results are the public page https://app.nassaucountyny.gov/BOE/results/election2.html. The report stamp is November 5, 2026, 8:50:53 p.m. ET. The file was last modified November 5, 2026, 9:21:02 p.m. ET and fetched November 6, 2026, 9:56:48 p.m. ET. The header says 538,876 ballots and 1083 of 1083 precincts. That header is the whole report, not a precinct count for each contest.
News reports were checked November 6, 2026 at 10:28:30 p.m. ET (News 12, Patch); November 6, 2026 at 10:28:31 p.m. ET (South Shore Press, The East Hampton Star). They are context, not a canvass. The check date is America/New_York. Each source line also prints the server HTTP Date, which is GMT and can name the next calendar day.
This page's own calendar date is 2026-11-06 in America/New_York. That date is separate from the result timestamps above. A certification date is not stated, because these files do not give one.

The arithmetic
Suffolk has 40 contests, 1,070 unique election districts, and 12,736 election-district by contest rows. Nassau has 53 contests and no election-district rows.
A contest total is the sum of the candidate lines in that contest, including every write-in line. For a vote-for-several contest those are candidate vote marks, not ballots and not voters. Blank ballots, void ballots, over-votes, and under-votes are not in the denominator, because this snapshot does not publish them. Suffolk's ballotsCast field is 0, so no county ballot total is invented.
The displayed percent is 100 times write-ins divided by contest marks, rounded half up to two decimals. Ranks do not use that rounded percent. A count rank sorts the write-in count. A rate rank sorts the exact fraction write-ins divided by contest marks. A tie shares a rank and the next rank skips, so two districts tied for first produce ranks 1, 1, 3. Tied districts are listed by name.
Rate rank starts at 100 contest votes. Without that floor, Islip 220 would lead the County Clerk rate list at 2 write-ins out of 2 contest votes. A district under the floor is left unranked. It is not entered as zero and it is not given a rate color on the map.
An election district missing from a contest is outside that contest. It is not stored as zero. A printed zero stays a zero. The three not-reported districts are Brookhaven 057, Islip 008, Southold 001. The breakdown still prints numbers for them, those numbers stay in the published totals, and the map hatches them.
Nassau prints one write-in line per seat. The lines are added. Supreme Court is 3,446, the sum of eight lines. Family Court is 1,671. District Court District 2 is 1,179. Keeping only the first line would be a smaller and wrong number. Named candidates already include their party lines, and those party lines are not added again.
A district contest uses only the election districts in that contest's file. Congressional District 3 in these files is a Suffolk portion and, separately, a Nassau portion. The two are not added. There is no step that removes a person who wrote in for more than one office, because these rows are contest marks, not identified voters.
These published returns do not identify recipients. A missing name is not a zero. News reports are context, not a canvass, and no total on this page is assigned to a named person.

The map join
The polygons are the file already used by the Suffolk results map and the swing map: site/results/mapdata/suffolk-eds.geojson. The results-map record says they were saved 2026-11-04T09:29 from Suffolk County GIS, Election Districts layer. The same record's results clock is 2026-11-04T05:24:37.9924553Z. This page did not download a new boundary. The saved file does not include a separate revision date for the GIS layer, so that date is not stated.
A polygon joins a results row only when the town and the election-district number both match. The geometry name Brookhaven ED# 235 has the key brookhaven|235. The results name Brookhaven 235 has the same key. The number 235 alone is not used, because more than one town has a district 235. The GIS field MUNICIPALITY is a hamlet or village, such as Farmingville, and it is not the town.
The join audit matched 1070 result districts to 1070 polygons. Unmatched result districts: 0. Unmatched polygons: 0. Duplicate polygon keys: 0. The build stops if any of those are not zero, rather than dropping a district or painting it as zero.
On the map, gray means outside the selected contest. A pale district can be a measured zero. A hatched outline means not reported. In rate mode, a district with fewer than 100 contest votes keeps a separate color and is not treated as a high rate or as a zero. The color bins are nearest-rank quarters of the positive values in that contest. The upper edge is included in the bin. The same edges are in the legend and in the downloadable data.
Congressional, senate, assembly, and town codes on the polygon are not used to decide eligibility. The contest's own rows do that. Nassau published no election-district file, so Nassau has contest bars and no election-district map. No Nassau number is spread across a shape.
