Chandler voters appear to have passed an amendment to the city's charter that would move up the date of the August primary. Not all ballots have been counted as of March 10.

A new Arizona state law requires that beginning in 2020, the primary election for nonpresidential races will be held on the first Tuesday in August. Chandler's primary elections had historically been on the last Tuesday in August. The amendment will put Chandler in compliance with the new state law.

With 35,875 ballots cast and turnout at 22.84%, the proposition to amend the charter was passing at 92% as of March 10, with 2,735 people voting against, according to data from the Maricopa County Elections Department. The election was an all-mail election.
