2026 Polling Sources

Polling for the 2026 U.S. midterms is already underway — Senate, House, governor, and generic congressional ballot surveys are released weekly. House district polling is much thinner than Senate or governor polling; only competitive districts tend to get repeated surveys, which is why the national generic ballot matters for estimating House control. This directory lists nonpartisan pollsters alongside left- and right-leaning firms and aggregators in equal number — compare partisan sources against neutral benchmarks before reading toplines.

Pollster — fields voter surveys Aggregator — collects or averages others' polls (includes forecast models and expert raters)

RealClearPolling

Aggregator Right

The most useful single starting point for raw 2026 polls. Lists individual surveys by race — Senate, governors, generic congressional ballot — often within days of release. August 2026 feeds include Texas Senate, North Carolina Senate, Michigan primaries, Arizona governor, Wisconsin governor, and more. Sister site RealClearPolitics is editorially conservative; headline selection on the broader RCP network can feel right-leaning.
