Political Direct Mail for South San Francisco campaigns means targeted USPS mail drops to high-propensity voters using the current county file — sized to the San Mateo County voter universe rather than a national template. South San Francisco has roughly 67,000 residents and 32,000 registered voters, which puts most local races inside a small-universe playbook where political direct mail is decisive. South San Francisco's transformation into the 'Birthplace of Biotechnology' has created enormous commercial growth alongside affordable housing challenges. Campaigns must bridge longtime working-class residents and biotech industry newcomers. Our political direct mail program supports South San Francisco candidates running for South San Francisco City Council (5 members) and South San Francisco Unified School District, plus county and ballot-measure efforts in San Mateo County.
