Early voting has only just begun, but the race for the governor’s office may already be over.

Public health advocates urged voters Tuesday to support a renewable energy mandate on the November ballot even though not one of them could say how much of a difference it actually would make in ground-level air pollution.

It ultimately may not matter if Arizonans vote in November to require utilities to generate more of their electricity from renewable sources.

Democrat Sandra Kennedy said Thursday there would be no need for voters to impose a renewable energy mandate if state utility regulators would do their job.

A key aide to Attorney General Mark Brnovich altered language of the ballot description of Proposition 127 that the state's top elections officer called "eyebrow raising'' and the lawyer for initiative organizers said is designed to help Arizona Public Service convince voters to reject it.

Arizonans are going to get a chance to decide whether they want to require utilities in the state to produce more of their power from renewable sources.

Former Corporation Commissioner Sandra Kennedy has easily claimed one of two Democratic nominations for two open Arizona Corporation Commission seats.

The Democrats don't even have a gubernatorial candidate yet. But that hasn't kept the Republican Governors Association from already spending more than $9.2 million to ensure that Doug Ducey gets another four-year term, virtually all of that for commercials to attack David Garcia.

The fight over whether Arizonans get to vote on a renewable energy measure has turned into the clash of the financial titans.

The question of whether voters get to decide whether to outlaw ``dark money'' could depend on whether a judge voids a law that throws a hurdle in the path of initiative organizers.
