View Maryland counties →Download CSV All state notes

File: MD.csv (24 rows: 23 counties + Baltimore City, FIPS 24510; Baltimore County is 24005). Columns: d = Democratic, r = Republican, o = all other U.S. House votes (Libertarian, Green, unaffiliated, "Other Write-Ins", and named write-in candidates). Votes are summed over all eight "Representative in Congress" contests in each county, across all vote types reported.

Sources

2022 (certified): Maryland State Board of Elections precinct-level results file https://elections.maryland.gov/elections/archive/2022/election_data/GG22_AllPrecincts.csv (Last-Modified Wed 08 Jan 2025 02:49:28 GMT). Office "U.S. Congress"; votes = Early + Election Night + Mail-In Ballot 1 + Provisional + Mail-In Ballot 2.
2026 (unofficial): SBE "County Break Down" pages, one per district: https://elections.maryland.gov/elections/2026/general_results/gen_detail_results_2026_4_N_District%20N.html for N = 1…8 (e.g. https://elections.maryland.gov/elections/2026/general_results/gen_detail_results_2026_4_6_District%206.html). As of: all eight pages "Last refreshed: 11/09/2026 08:27:52 PM" (ET); downloaded 2026-11-09 ~9:25 pm ET. Each page shows all election-day precincts reported (e.g. 214 of 214); provisional column is "NR" (not yet reported).

Validation (sum of county rows vs statewide totals)

Year	Column	Our sum	Reference	Diff
2022	D	1,291,446	1,291,446 (FEC)	0
2022	R	690,463	690,463	0
2022	Other	13,819	13,819	0
2026	D	1,421,853	1,400,912 (Nov 9 6:10 pm ET aggregate)	+20,941
2026	R	625,643	623,050	+2,593
2026	Other	25,919	(not reported)	—

2022 matches exactly. 2026 is higher than the national aggregate because the SBE pages we used were refreshed at 8:27 pm ET, after the 6:10 pm reference snapshot; Maryland is still canvassing mail-in ballots (which skew Democratic), so the gap is mostly D. All eight districts are included (each county's sum across districts checks against the page totals).

Districts without a D or R candidate

2022: none — all 8 districts had both a DEM and a REP nominee.
2026: none — all 8 districts had both a Democratic and a Republican nominee.

Caveats

2026 numbers are unofficial; mail-in canvass continues and provisional ballots are not yet reported ("NR"), so totals will rise.
2026 District 3 had a write-in candidate listed as Republican (Robert L. Coffman, 11 votes statewide). Write-in candidates are counted in o, not r, so r reflects only the ballot nominee.
o includes "Other Write-Ins" in both years.
