FiveThirtyEight Polls Data (CSV archive)

FiveThirtyEight Polls Data (CSV archive) is a rest api from FiveThirtyEight / ABC News providing politics & elections data. FiveThirtyEight's public polling dataset: free CSVs of presidential, Senate, House, governor, generic-ballot and approval polls plus computed polling averages, historically the canonical aggregate for pricing US election markets against the crowd. IMPORTANT: ABC News shut down FiveThirtyEight in March 2025; the live auto-updating CSV endpoints (projects.fivethirtyeight.com/polls-page) now 302-redirect to abcnews.go.com and no longer serve data. What remains is a frozen GitHub archive (averages through the 2024 cycle), not a live feed — bots needing current polls should treat this as historical-only and migrate to a maintained source.
