Republican Mark Napier has a huge lead over his GOP challengers as the early votes have been counted, having captured 42 percent of the vote. None of the other candidates have broken 20 percent.
"We worked really hard," Napier said. "I had an amazing group of volunteers. The voters of Pima County heard the message and it looks real good."
Napier said he was looking forward to challenging longtime Pima County Sheriff Clarence Dupnik in November.
"It's time for a new sheriff," Napier said.
