The closely contested yet Democratic-leaning Arizona governor race between incumbent Katie Hobbs and challenger Andy Biggs, with recent polling averages showing Hobbs ahead by roughly 6-7 points, anchors trader expectations for total ballots cast on November 3 in the 2.45M-2.9M range. Midterm dynamics, including Democratic enthusiasm from the incumbent's position and Republican mobilization efforts amid rising ad spending, support modest growth over the 2.29 million votes recorded in 2022. Uncertainty around independent turnout, early and mail voting patterns, and ground-game execution in a non-presidential year keeps the three leading brackets tightly bunched, with separation likely to emerge from final-week mobilization data or shifts in voter participation among key demographics.
