Louisiana: sources, checks and caveats

File: LA.csv (64 parishes). Columns: d = all Democratic (DEM) candidates combined, r = all Republican (REP) candidates combined, o = everyone else (LBT, IND, NOPTY). Votes are summed over every "U. S. Representative -- nth Congressional District" contest on the parish's ballot. Both years use the November election ballot (Louisiana's open "jungle" primary for U.S. House), not the December runoff.

Validation (sum of parish rows vs statewide totals)

2022 matches the FEC exactly, and each district's parish sum equals the SOS district total. In 2026 our totals are slightly higher than the national aggregate. CNN's feed (extracted 02:35 GMT Nov 10) showed D 645,815, R 789,455, O 23,905 at 99% reporting, so the gap comes from timing and rounding between aggregators, not from a missing district.

Election structure

• 2022: On Nov 8 Louisiana held an open (jungle) primary for U.S. House. All candidates of every party appeared on one ballot, and a candidate with a majority was elected outright. All 5 contested seats were decided on Nov 8 (Outcome = Elected), so no House race went to the Dec 10 runoff. CD4 (Mike Johnson, R) was unopposed and was not on the ballot, so it has no votes (FEC lists it as "Unopposed").
• 2026: The House races on Nov 3, 2026 were again a single open ballot. The SOS race metadata has IsClosedParty = 0 and CanHaveRunoff = 1, and several districts had more than one candidate from the same party. The closed party primaries held earlier in 2026 (May 16, with a June 27 runoff) included only the U.S. Senate party primaries and no U.S. House contests. So the 2026 November House structure is the same as 2022, and both years count every candidate on the November ballot. All 6 districts were on the ballot. Four were decided outright (CD1 Scalise, CD2 Carter, CD3 Higgins, CD4 Johnson). CD5 and CD6 go to the December 12 runoff: CD5 Patricia "Pat" Moore (D) vs. "Gabe" Firment (R), and CD6 Chauna Banks (D) vs. Blake Miguez (R). The reasons for the change from the closed-primary system that Louisiana had adopted for 2026 are not documented in the results data.

Districts without a D or R candidate

• 2022: CD4 had no D and no R votes because the race was not on the ballot. CD6 had no D (Graves R, Belzer R, Craig LBT). All other districts had both. The brief said "1 district with no R per FEC", but the FEC file does not support this: every 2022 LA district with votes had at least one R. CD2 had Lux (R) against Carter (D).
• 2026: none. All 6 districts had at least one D and one R. CD5 had 6 R and 3 D candidates, including Oscar "Omar" Dantzler, who ran as a Democrat in 2022 and is listed as REP in 2026.

Caveats

• 2022 zeros: 15 parishes lay entirely in CD4 in 2022 (Allen, Beauregard, Bienville, Bossier, Caddo, Claiborne, De Soto, Evangeline, Natchitoches, Red River, Sabine, St. Landry, Union, Vernon, Webster). They had no U.S. House contest on the ballot, so d22 = r22 = o22 = 0. Treat these as "no contest", not as zero support. Parishes split between CD4 and another district have only the non-CD4 portion in 2022. Livingston also has d22 = 0 because it was entirely in CD6, which had no D.
• The 2026 district boundaries differ from 2022: CD4 covers different parishes and the district composition changed, so parish totals are "all House votes cast in the parish" rather than like-for-like district comparisons.
• 2026 results are unofficial. Party labels come from the SOS candidate labels (DEM / REP / LBT / IND / NOPTY).
