Source notes · U.S. House by county, 2022 vs 2026
Arizona: sources, checks and caveats
File: AZ.csv (15 counties). Columns: d = Democratic (DEM), r = Republican (REP), o = all other U.S. House votes (independents, Libertarian, Green, No Labels, and all write-ins, including write-in candidates who list a D or R party). Votes are summed over every "U.S. Representative in Congress - District No. n" contest that touches the county.

2022 matches exactly. The 2026 gap is explained by timing: our snapshot is about 1h20m newer than the national aggregate, and Arizona (Maricopa above all) is still counting late early ballots.
Districts without a D or R candidate
- 2022: CD8 (Lesko) and CD9 (Gosar) had no Democratic nominee, so D = 0 from those districts. Their Democratic write-ins (Spreitzer 5,145 and Guzman 2,013 in CD8, Grayson 3,531 and "Tom T." 858 in CD9) count as other, the same way the FEC codes them (W).
- 2026: CD3 had no Republican on the ballot. Jacob Parkman (REP, write-in, 1,622 votes) counts as other, the same rule as 2022. All other districts had both a D and an R nominee.
Caveats
- 2026 numbers are unofficial, and Arizona typically has many ballots still to count several days after the election. The statewide canvass is scheduled later in November.
- Redistricting: both years use the 2022–2031 IRC map, so the district lines are the same.
- 2026
o includes "Unassigned/Unofficial Write-in" lines as reported. Nothing in these files was estimated.
