About these results
Shares count all candidate votes, including write-ins, with a candidate's votes on several party lines added together. Each result is on the lines in force at the time. Mid-decade redraws before 2016 may be unmarked.
President in this district: 2016 and 2020 are estimates: precinct votes are split between districts by census block.
Counties only partly inside the district show the 2024 result for that part; estimates are labelled.
Margin chart: winner minus runner-up. Gaps are unopposed races; dashed lines are new district lines.
