Gallego managed to lock down his base and then reach out to the middle: he ran as a Marine veteran and the son of Latino immigrants, put experience front and center, and offered clear, practical stances. He didn’t get sucked into left-wing activism that would have scared off moderates.

Polling averages in the run-up to November (FiveThirtyEight, October 2024) consistently showed Gallego ahead, with little volatility. In Maricopa County, the state’s swing powerhouse, Gallego beat Biden’s 2020 numbers by four points.
