While Moore is his strongest opponent, but he is not considered a serious threat to the second term Villaraigosa hopes to earn on Tuesday.
"I'd just like to say to the people of Los Angeles, it's been an honor to work for you for three and a half years. I'd be honored to have another term," Villaraigosa said.
Gruel voted Tuesday morning in Studio City, while Patsouras voted absentee.
Kathleen Suzy Evans is also on the ballot for city controller.
In the race for city attorney, Rocky Delgadillo has termed out, leaving the seat open for five candidates.
Two of the top names on the ballot include Jack Weiss and Carmen Trutanich. Trutanich has been endorsed by L.A. County D.A. Steve Cooley and Sheriff Lee Baca, while Weiss has endorsements from LAPD Chief Bill Bratton and Villaraigosa.
"I hope the people give me a chance to be the next city attorney," Weiss said.
Trutanich voted absentee, but still showed up at his polling location, acknowledging he had already voted.
Eight city council seats are up for grabs, as are three school board member positions.
A record-low turnout was expected at Tuesday's polls, perhaps as low as 10 percent.
"Please come out and vote, whether you vote for me or not," Villaraigosa said.
Polls closed at 8 p.m. Tuesday.
