San Diego's large active-duty and veteran population coexists with a majority-minority electorate shaped by Latino growth along the South Bay corridor, producing a metro that swings on suburban turnout in mid-cycle elections.

The 2008 election was the turning point, when the Democratic candidate carried the metro by ten points. The 2024 margin was seventeen points, in line with the metro's new direction.

The demographics suggest why. A population of 3,288,774, a 48% non-Hispanic-white share, and a median household income of $106,268 situate the metro in the broader realignment patterns of recent cycles.
