Early Voting in Ada County, Idaho Underway Through May 15 at Nine Locations Across the Treasure Valley
Ada County, Idaho — Early voting for the May 19 primary election is now underway in Ada County, giving Treasure Valley residents more than two weeks to cast their ballots at nine polling locations spread across Boise, Meridian, Eagle, Star, and Kuna. Polls are open from 8 a.m. to 5 p.m. Monday through Friday, May 15, and voters may cast their ballot at any of the available sites — including two newly added locations this election cycle.
What Ada County Voters Need to Know Before Heading to the Polls
This is a partisan primary election, meaning voters may only cast ballots for candidates who align with their registered party affiliation. The races on the ballot span a wide range of offices critical to Ada County and the state of Idaho, including candidates for Congress, governor, state and legislative offices, county commissioners, and judges.
For voters who want to review their choices ahead of time, the Ada County Elections website offers a “view my ballot” option that allows residents to see exactly what will appear on their individual ballot before arriving at a polling location. Officials encourage voters to take advantage of this tool to help speed up the voting process and come prepared.
Residents who are not yet registered to vote are not out of options. Same-day voter registration is available at any of the nine early voting locations. Those looking to register and vote on the same visit must bring a valid photo ID and proof of residence to complete the process.
