Limits of this data

This is a what-if tool, not a forecast. Turnout effects come from who pollsters' likely-voter screens leave out, which differs by pollster, and real turnout surges are local and lopsided rather than uniform.

Paired LV/RV polls are a minority of polls, and a race's gap from two or three of them is noisy — that's why it's pulled toward the national gap.

Unpolled races use a partisan baseline that misses individual Senate results by about 10 points (typical deviation in 2014–2022), more than polling averages do.

District leans are Cook PVI on the lines the source lists; districts redrawn for 2026 may lean differently.
