Part of Iowa Voter Check

This is the Benton County page of Iowa Voter Check, a project of True the Vote, pointing Iowa voters at the official tools that already exist — and at Scan Check Protect to verify your registration.

Where anything here differs from what Benton County or the Iowa Secretary of State publishes, they are right and this page is not.
