Author: KTVB Staff, Joe Parris Published: 10:59 AM MST March 10, 2021 Updated: 6:47 PM MST March 10, 2021 Nearly 18,000 voters in Ada County who did not cast a vote in an election during the past four years have been removed from the voter rolls. Ada County elections officials say this is part of a statewide effort to update voter records. Every two years, Idaho code mandates the cancellation of inactive voter records to ensure that Idaho’s statewide voter registration system is current. Officials say this is the final clean-up to ensure that voters who have moved or are otherwise ineligible to vote are removed from the voter rolls.
