Maryland’s 1st Congressional District remains a solidly Republican seat heading into the November 2026 general election, with incumbent Representative Andy Harris positioned to retain the seat based on the district’s R+8 Partisan Voter Index, his repeated victories since 2011, and consistent nonpartisan ratings classifying the race as Solid or Safe Republican. Harris secured his party’s nomination with roughly 80 percent in the June primary and maintains a substantial fundraising lead over Democratic nominee Dan Schwartz, who prevailed in a four-candidate primary. A July poll showed Harris ahead 52 percent to 39 percent. Broader midterm dynamics and ongoing state-level redistricting discussions for future cycles have not altered the current outlook. Late developments such as a significant national shift or unforeseen local controversy could narrow the margin, though structural advantages continue to favor the Republican outcome.
