PHOENIX (AP) -- It appears the Phoenix mayoral race will be decided by a runoff election early next year.
Unofficial results Tuesday night showed Kate Gallego and Daniel Valenzuela as the top vote-getters, but neither had at least 50 percent plus one vote to win.
Gallego was at 45 percent and Valenzuela at 26 percent.
The other candidates who ran were Moses Sanchez and Nicholas Sarwark.
A runoff if needed has been scheduled for March 12.
The special election was held to replace Greg Stanton, who left office in May to run for U.S. Congress. He was elected Tuesday night.
