Sources

Both years come from the SC Election Commission's Clarity ENR site (listed at https://scvotes.gov/elections-statistics/election-results/). The data is the statewide detailxml.zip, which has county-level votes for each choice in every contest. Rows used: contests "U.S. House of Representatives, District 1–7". County values are the sum of all vote types for that county (early, absentee, election day, provisional, failsafe, and so on). - 2022 (certified): https://www.enr-scvotes.org/SC/115412/313728/reports/detailxml.zip (election page https://www.enr-scvotes.org/SC/115412/). The file timestamp is 11/17/2022 3:17:28 PM EST. - 2026 (unofficial): https://www.enr-scvotes.org/SC/127300/386034/reports/detailxml.zip (election page https://www.enr-scvotes.org/SC/127300/web.345435/#/summary; current_ver.txt = 386034 when fetched 2026-11-10 02:06 UTC). - 2022 cross-check: OpenElections openelections-data-sc 2022/20221108__sc__general__precinct.csv gives the same statewide D, R and other totals exactly. - County FIPS: Census 2020 national_county2020.txt.

2026 as-of

2022 matches exactly. In 2026 the source's county rows add up to each candidate's total for every contest. The 2026 sums are a little above the national aggregate, even though SC's file timestamp (Nov 6) is earlier than the aggregate's as-of time. The national aggregate most likely used an older SC snapshot.

Districts without a D or R candidate

2022: District 3 had no D (Duncan R plus write-ins). District 4 had no D (Timmons R plus write-ins). Every district had an R.
2026: Every district (1–7) had both a D and an R.

Caveats

"o" includes write-ins and minor-party candidates: ALN and GRN in 2022; LIB and WRK in 2026.
Because District 3 and District 4 had no D in 2022, d22 = 0 in Abbeville, Anderson, Edgefield, Greenville, Greenwood, Laurens, McCormick, Newberry, Oconee, Pickens and Saluda, because those counties were entirely in District 3 or District 4.
