Source notes · U.S. House by county, 2022 vs 2026

New Jersey: sources, checks and caveats

File: NJ.csv (21 counties). Columns: d = Democratic, r = Republican, o = all other U.S. House votes: named non-D/R candidates, plus write-ins where the source reports them. Votes are summed over every congressional district contest in each county.

Sources

• 2022 (certified): NJ Division of Elections official list, U.S. House (county breakdown per candidate) https://www.nj.gov/state/elections/assets/pdf/election-results/2022/2022-official-general-results-us-house.pdf (dated 01/18/2023; Last-Modified 16 Feb 2023). Party is taken from each candidate's ballot slogan: "DEMOCRATIC" goes to d, "REPUBLICAN" to r, and every other slogan (Libertarian, Socialist Workers, independents' slogans) to o.
• 2026 (unofficial): the state has not posted 2026 results (the official US House PDF URL returns 404), so each county clerk's latest posting was used:

• FIPS codes: Census national_county2020.txt.

Validation (sum of county rows vs statewide totals)

2022 matches exactly. The 2026 gap is unresolved. Checks done: - No district is missing: every county has all the districts it touches, and all 12 districts are present. - No county is double counted. - The district totals are plausible (see below).

The most likely cause is that the county postings and the national aggregate were taken at different times, with several counties (Middlesex, Monmouth, Passaic, Camden, Mercer) updated on the evening of Nov 9, after 6:10 pm. That has not been verified. Several other counties are older than the national aggregate (Nov 4–7), so timing alone may not explain the whole gap.

2026 district totals (D / R / O): CD1 181,237 / 76,276 / 876 · CD2 137,328 / 130,067 / 2,936 · CD3 173,644 / 97,620 / 5,573 · CD4 108,846 / 156,626 / 322 · CD5 170,160 / 94,145 / 8,432 · CD6 148,007 / 65,188 / 896 · CD7 190,240 / 136,491 / 5,634 · CD8 109,182 / 0 / 14,979 · CD9 123,604 / 58,868 / 3,079 · CD10 152,118 / 27,727 / 234 · CD11 170,225 / 107,223 / 2,873 · CD12 167,097 / 66,237 / 4,166.

Districts without a D or R candidate

• 2022: none — all 12 districts had both a Democratic and a Republican nominee.
• 2026: CD8 had no Republican (Menendez, D, vs three independents; Hudson, Essex and Union portions). Those counties' r26 from CD8 is 0, which is why Hudson's r drops from 26,696 to 6,986.

Caveats

• 2026 numbers are unofficial and come from 21 separate county postings of different ages:
• Atlantic, Cape May, Hudson and Salem are election-night or Nov 4.
• Bergen, Morris, Hunterdon, Cumberland, Gloucester and Ocean are Nov 5–6.
• Somerset is Nov 7; the rest are Nov 9.
• Cape May's later postings (and the state's periodic reports) give ballot counts only, not candidate votes.
• Totals will change as mail-in and provisional ballots are counted.
• Bergen's posting has mail-in ballots only partly counted.
• 2026 o:
• It includes write-ins wherever the county reports them. Essex's feed has no write-in lines, so its o is ballot candidates only.
• Bergen and Burlington o = contest total − D − R.
• Burlington leaves out 9 unresolved write-ins.
• Hunterdon's "Not Assigned" line, which repeats its write-in total, was not counted twice.
• In 2022, Hunterdon and Warren (CD7 only) have o = 0 because no third-party candidate ran there. That is not missing data.
