Colorado congressional districts
"House vs. 2024" compares the 2026 House margin with Harris's 2024 margin inside the district's current lines (NBC News's district baseline); it is blank where only one party ran, where two candidates of one party met in a top-two race, or where NBC has no 2024 baseline. "Top race, from its counties" averages the county Dem movement of the district's counties, weighted by each county's House votes.
