The Green Party candidate, political newcomer Angela Green, has garnered up to 6 percent of the vote in recent polls. Polling averages show McSally and Sinema separated by a point or two.

Green’s message to her supporters: “I want them to vote for a better Arizona, and that would be for Kyrsten Sinema…. What I’m looking to do to help Arizona become more green again. After watching the debates and seeing everything, Sinema’s stance on a lot of things are very close to mine.”

Green Party voters’ values have been more closely aligned with Democrats than Republicans. Third-party votes also tend to be protest votes against the mainstream candidates.
