U.S. House
Each result reflects the U.S. House district as it was drawn for that election; redistricting has redrawn these lines over time, so they can differ from the current 120th-Congress district shown on the map above.
Congressional District 11 delivered R+21 in 2024, the most recent presidential result on the lines as drawn today. Across the presidential elections covered from 2008 through 2024, the district reached its strongest Republican margin of R+25 in 2016. The results across that span describe a consistent Republican lean, with the 2024 margin sitting four points below the 2016 peak.

About 31 percent of residents held a bachelor's degree or higher in the same estimate. The median age was 40.2 in the 2024 ACS five-year estimate.
