Voter purge

Voter roll

The official register of eligible voters — its accuracy sets the ceiling on election quality, and both inflation and wrongful removal are integrity failures.

Disenfranchisement

The loss or denial of voting rights, whether by law, administration or obstruction — its effect is measurable regardless of whether the intent can be shown.

Provisional ballot

A ballot cast when eligibility cannot be confirmed at the polling place, counted only once eligibility is verified — a safeguard against wrongful turn-away.
