Marc Victor's voters are obviously supporting Lake in the gubernatorial race. Lake is at 49% in this poll, while Masters is at 46% and Victor is garnering 3%. Hobbs is also at 46%, 1 point behind Kelly, who is at 47%. This seems to be an indicator that not much ticket-splitting is occurring in Arizona between Kelly and Lake, certainly not as much as it seemed at first. The third-party vote is making the difference between the two races. Kelly may have Victor to thank in helping him win reelection.
Polls tend to overestimate 3rd party support though. I'd be surprised if Victor gets more than 2% of the vote.
