A 21-year veteran of the Phoenix Police Department and former head of the Silent Witness program will take on Sheriff Joe Arpaio next November.
Paul Penzone filed the signatures he needed to get on the ballot Wednesday. His message: it's time for a change at MCSO.
Paul Penzone needed just over 2,500 signatures. He filed over six thousand.
"It is my honor to be here today. I look at today and I state to you this is the day we begin our journey to restore integrity to the Maricopa County Sheriff's Office," Penzone told supporters.
Penzone is a Democrat who has the support of Republicans including former U.S. Attorney Paul Charlton.
"We give the sheriff more authority than any other elected official in this state and when we discover the sheriff is abusing the power he is sworn to uphold, then we need to bring someone else in here," said Charlton.
Penzone says his campaign will focus on public safety, integrity and fiscal responsibility.
"This is a bipartisan effort to be nonpartisan in law enforcement. It is about public safety and not public image. We cannot tolerate anyone in leadership who is not serving our needs or our best interests."
Paul Penzone acknowledged he has a lot less money than Sheriff Arpaio, but he says he will be able to overcome that disadvantage.
One way to do that: he plans to challenge Joe Arpaio to a debate.
Scottsdale Police Lt. Mike Stauffer, a Republican turned Independent, is also running against Joe Arpaio.
