Bay AreaMore from California

Issue

Contra Costa County's Measure B, a 0.625-cent sales tax projected to raise about $150 million a year for five years, failed on the June 2 ballot. The county's June 5 count showed about 42.1% yes and 57.9% no. It is the first California county tax to backfill Medicaid cuts that lost in 2026.

Key points

  • Measure B, a 0.625-cent tax worth about $150 million a year for five years, failed about 42% to 58%.
  • Contra Costa Health, which runs the county hospital, clinics, and a health plan of about 270,000 members, has no local backstop for H.R. 1 losses.
  • County backfill taxes now stand at two wins, Santa Clara's Measure A and LA's Measure ER, and one loss in Contra Costa.
