U.S. House
Each row is a county-allocated estimate of U.S. House votes for this district — county returns apportioned onto its boundary, not precinct-counted. “Vote lead” is the estimated local lead here, not necessarily the winner of the full contest.
Assembly District 105 anchors the southwestern corner of Staten Island, where working-class homeowner demographics and a decades-long rightward shift have made it one of New York City's most reliably Republican legislative seats.
Across the recorded series it reached a Democratic high of 9.3 points in 1964 and a Republican high of 67.0 points in 1956. Between 2020 and 2024 the district moved 5.9 points toward the Republican candidate; the 2024 margin was 12.2 points.
A population of 137,050, a 70% non-Hispanic-white share, and a median household income of $111,059 describe the district. The district's voting pattern over the last decade is most similar to that of Assembly District 94 and Assembly District 13.
