How this rating is calculated

Every approval rating on USApprate is community-driven. Visitors vote "Support" or "Oppose," and we turn those votes into a single percentage using a simple, transparent formula:

Approval Rate = (Support Votes ÷ Total Votes) × 100%

To keep results fair, each visitor is limited to one vote per official or party through privacy-preserving browser fingerprinting, and you can change your vote at any time without creating an account.

These numbers capture grassroots sentiment from people who visit USApprate — they are not scientific polls and are not a statistically representative sample of all Americans. Think of them as a real-time pulse of engaged citizens that complements professional polling. For survey-grade data, we recommend established organizations such as Gallup, Pew Research Center, and our full methodology.
