This runoff election was called when no candidate received more than 50 percent of the vote in the November election.

Gallego led the four-person field with 45 percent of the vote. Valenzuela was second, at 26 percent.

Voting in the special election has already begun.

Mail-in ballots were sent out Wednesday to voters on the permanent early voter list. Voters who want an early ballot and haven't signed up can request one by March 1.

Also on the March 12 city ballot, voters in Gallego's and Valenzuela's former council districts will select their successors.

There are seven candidates on the ballot in Gallego's District 8, covering south Phoenix and Laveen: Gilbert Arvizu; Carlos Garcia; Mike Johnson; Lawrence Robinson; Camaron Stevenson; Warren Stewart Jr.; and Onesimus Strachan.

In Valenzuela's District 5, covering west Phoenix, there are four candidates: Audrey Bell-Jenkins; Betty Guardado; Vania Guevara, a former Valenzuela staffer who was appointed to fill the seat; and Lydia Hernandez.

The mayor's seat is vacant after former Mayor Greg Stanton resigned to run for Congress. He won that election and serves Congressional District 9.

Thelda Williams has been serving as interim mayor.
