Republican. Maryland’s 1st District. Re-elected on November 3, 2026.
Lean is the Cook Partisan Voting Index (PVI) on the district’s 2026 election lines: R+10 and up is solidly Republican, R+5 to R+9 lean Republican, D+4 to R+4 swing, D+5 to D+9 lean Democratic and D+10 and up solidly Democratic. A 2032 redistricting flag marks one of seven states American Ascent watches for the maps drawn after the 2030 census, with who draws the map there.
Leadership posts and committees in the 119th Congress, as the Clerk of the House listed them on October 1, 2026; the 120th Congress names its own when it convenes on January 3, 2027. Chairman and Chairwoman are written as Chair. A gold mark names a leadership post. Years in the House come from the public congress-legislators record of every member’s terms.

Facts from free public data: the TV markets the district sits in, what every campaign and outside group spent in recent races, and the votes cast. Spending is campaign spending, less contributions to party committees and other candidates, plus independent expenditures. A vote is any vote cast in that contest.14
| Market | TV homes | Of the district | District is, of market |
|---|---|---|---|
| Baltimore, MD (rank 29) | 1,155,000 | 72.4% | 18.4% |
| Salisbury, MD (rank 131) | 198,930 | 27.6% | 47.3% |
Markets are Nielsen’s Designated Market Areas, matched to the district county by county on the 119th Congress lines (11 counties or parts). Shares are of people, from the 2020 Census. TV homes are Nielsen’s 2024-25 estimates. A small share of a large market means most of what a TV buy reaches lives outside the district.10

Conservative average
91.1
Heritage Action and Turning Point Action are the member’s lifetime scores, read from those pages. Club for Growth is the member’s lifetime rating, and GOP Platform measures agreement with the national Republican Party platform in 2025, published by the Institute for Legislative Analysis.
The scorecard average covers all four. No score means none was published, not zero, and is left out of the average: the record says “No score published”.
Each group’s name links to the member’s own page on its scorecard, opened on the date shown.
Progressive average
8.7
Mirrored for every member, of either party: the League of Conservation Voters’ lifetime score, read from the member’s page; Progressive Punch’s lifetime score on all votes, read from its House table; and Democracy Defenders Action’s Stop Corruption Now score for the 119th Congress (September 16, 2026), its total on 10 anti-corruption and pro-democracy votes and cosponsorships, shown out of 100. The progressive average covers the three; no score means none was published (Stop Corruption Now did not grade members in office for less than a year, or certain current and former House leaders).
The Immigration Accountability Project’s IAP Action score counts sponsorship, cosponsorship, and votes on immigration. A running total, not a percentage. Higher means more restrictive on immigration.

One public poll of the 2026 race, newest first. Harris’s share is always on the left. Red is a Republican candidate, blue a Democratic one.
Shares are as published, so they add up to less than 100 when some voters were undecided. The line at the middle marks half the vote. The pollster’s name links to the poll’s release or the news report of its results.
