More than 200,000 people in Maricopa County have already made their voices heard in an election where every registered voter received a ballot in the mail.
It's the first major test for Maricopa County Recorder Adrian Fontes after unseating Helen Purcell, who held the office for 28 years.
Fontes said "it wasn't easy" at first to start making changes.
"I think that the office was really used to a particular culture and used to a particular way of doing things," he said.
Fontes told ABC15 his goal was to make the voting process faster, simpler and more secure. Hundreds of polling places were reduced to 27 ballot centers. Upgraded computer terminals allow voters to scan a drivers license or answer authenticating questions to reprint ballots, cutting down the need for provisional ballots, Fontes said. Computers engineers tried hacking the system and patched any potential vulnerabilities.
"There's been so much testing and retesting and checking and re-checking -- we've been very cautious as we moved forward," he said.
What about next election?
Amid questions about the clarity of ballots, Fontes said he will be meeting with voters and community leaders to identify any potential improvements. He described this election as a "test run" for an all-mail process, adding there have been very few glitches.
