Final, unofficial election results show Democrat Sandra Kennedy and Republican Justin Olson headed for victory in a four-way race for two seats on Arizona's Corporation Commission.
They maintained their leads Monday evening as Maricopa County, Arizona's largest, posted the final vote counts for Arizona.
A win by Kennedy would put a woman on a utility commission that currently has five male members. Kennedy is a former commission member and former lawmaker.
A win by Olson would let him keep the commission post-Republican Gov. Doug Ducey appointed him to.
The commission oversees service and rates charged by electric, water and natural gas utilities.
Republican Rodney Glassman placed a tight third for the two seats. Democrat Kiana Maria Sears was also on the ballot.
