Incumbent Democrat Dianne Feinstein won her second full term.

Despite touting his service as a moderate Republican representing a strongly Democratic district, Campbell was underfunded and a decided underdog against the popular, heavily financed Feinstein.

[5] Green Party candidate Medea Susan Benjamin finished second (ahead of Republican Tom Campbell) in six Northern California municipalities, most of which are in the San Francisco Bay Area: Oakland (10.18%), Emeryville (13.35%), Albany (14.37%), Fairfax (15.99%), Berkeley (22.23%), and Arcata (26.77%).

She tied with Jones for second place in Point Arena with 21.71% of the vote.

[6] Feinstein won 43 of 52 congressional districts, including 11 that elected Republicans.
