These are early, unofficial returns from NBC Bay Area's Contra Costa County results page. Totals were cross-checked against ABC7's results page, which matched or ran slightly ahead in its later updates.

San Ramon Mayor

  • Mark Armstrong: 76.03% (13,576)
  • Paschalis Ntatsos: 14.15% (2,527)
  • Emma Chigbu: 9.82% (1,753)

District 4

  • Marisol Rubio: 51.25% (2,166)
  • Jeffrey Joh: 48.75% (2,060)

ABC7 shows Armstrong at 76% (13,576).

All results are unofficial election-night and early-morning counts as of Wednesday, Nov. 4. Counties keep counting mail and provisional ballots for days, and certification comes later, so margins can shift, especially in close contests.
