An exclusive new ABC15/OH Predictive Insights poll of 589 likely voters shows Democratic candidate David Garcia with a sizable lead over his closest competitor.

As of Monday, Garcia has a 15-point lead over Steve Farley, with Kelly Fryer coming in third.

But pollster Mike Noble said there are a lot of likely voters still in play.

“Garcia currently has the advantage due to strong support among self-identified liberals, women and voter-rich Maricopa County,” said Noble. “With 28 percent of the likely democratic vote still undecided, it’s possible we could see a surprise come election night.”

The poll was conducted on August 14 and 15 through landline phone interviews. The margin of error is four percent.

Gov. Doug Ducey and former Secretary of State Ken Bennett will be facing off in the Republican primary.
