In an election facing Ward, Sinema holds a 10% lead, but 10% of likely voters remain undecided. A matchup against McSally is slightly closer, with Sinema ahead by 6% and another 10% of voters still undecided.

When paired up in a race against Arpaio, Sinema takes a huge lead, with 59% to Arpaio’s 33%, and only 8% of voters undecided.

In a historically red-leaning state, a Democrat in the lead may seem surprising. But OHPI polling expert Mike Noble says there are a couple factors boosting Sinema’s standing.

“The issue we are consistently seeing in the numbers is that Democrats are unified, Republicans are less united, and the all-important Independent voters are trending anti-Republican/Trump” said Noble, managing partner and chief pollster at OHPI.
