    Elections CenterThe Pima County Elections Department together with the Arizona Secretary of State will hold the official logic and accuracy testing for the March 17 Presidential Preference Election starting at 8 a.m. on Tuesday, Feb. 18 at the Elections Center, 6550 S. Country Club Road. Members of the public interested in seeing the process are invited to attend.

    As required by state law, the County’s Elections Department must conduct the logic and accuracy test prior to the start of early voting, which starts Feb. 19, and produce a 100 percent accuracy test before they can start counting ballots. Tuesday’s test will ensure all voting equipment used for the election reads and accepts the correct ballot types assigned and then accurately accumulates and reports the total number of votes for each candidate.

    State staff will test all vote tabulating equipment and its components. Machines used for the County’s voting system include the Election Systems and Software DS850, and Express Vote. Components of Express Vote include headphones and keypad for voters with vision disability.

    Members of the public who wish to attend should arrive by 8 a.m. The test should be completed by 10 a.m.

    The Presidential Preference Election on March 17 is being held by Arizona’s Democratic Party. To participate in this Election, voters must be registered as Democrats. Those who are not currently registered as Democrats and want to participate have until Feb. 18 at midnight to change their registration. The easiest way to do this is to go online at and select “Voter Registration.” The Arizona Republican Party has opted out of the Presidential Preference Election this year.
