The data from California's 2024 Senate primary reveals a coalition that looks less like a left-populist revolt and more like an upscale professional movement — with notable, specific exceptions in Latino renter precincts across Los Angeles and the Inland Empire.
In trades-heavy precincts, Porter's 2-party share against Schiff averages 31% — 5 points below her strongest showing in affluent professional precincts. Her working-class base, where it exists, is disproportionately Latino, renter, and urban.
Every dot is a California voting precinct where at least 50 voters marked a ballot for Porter or Schiff in the March 2024 US Senate primary. The dot is plotted at the precinct's population-weighted centroid. The trades view shows only the 3,246 precincts that fall in the top quintile of working-class concentration. The full statewide view shows all 12,075 precincts, with non-trades precincts rendered in muted gray.
The finding. Porter's 2024 coalition inverted the expected pattern. She ran strongest in affluent coastal professional precincts and lost ground as the trades index climbed. But within the trades universe, her hot spots cluster sharply: Latino renter precincts in East LA, the San Gabriel Valley, Inland Empire warehouse corridors, and Orange County's Santa Ana core. Her cold spots are disproportionately Black and white homeowner trades precincts — South LA, Moreno Valley, San Bernardino exurbs, Central Valley ag towns.
For field. The hot-spot list (1,058 precincts) is where Porter's brand already works despite a working-class demographic headwind. These are the precincts to reinforce. The cold-spot list (1,499) is where she needs new messaging — the coalition she'd need to build to win statewide in 2026.
