On the ballot
- Eric Jones — Democratic
- Mike Thompson — Democratic
This person holds your district's seat in the U.S. House of Representatives (2-year term).
Representative Mike Thompson led the June 2 primary with 41.0% and fellow Democrat Eric Jones took 22.2%, so November is a contest between two members of the same party. Jones raised $8,378,929 — $5,364,133 of it his own money, the largest self-financed campaign on this ballot — and still finished 19 points behind. The district covers Napa, Lake and part of the North Bay.
The winner holds one of 435 seats in the U.S. House for a two-year term. A member introduces bills, sits on committees that shape federal legislation, votes on the federal budget and on war powers, and handles casework between constituents and federal agencies. Seniority governs committee standing, and more than a quarter-century of it is a substantial asset for a district.
With two Democrats on the ballot, party is not the axis. The incumbent has 13 career bills enacted — the highest count of any candidate on this ballot — against a challenger with no record who has put more than $5.3 million of his own money into the race. Weigh a long legislative record against a self-financed challenge, and note the primary went decisively to the record.
Mike Thompson
Democrat, the sitting Representative for this district since 1999. He has sponsored 26 bills in the 119th Congress, and 13 of his career bills have become law — the highest enacted count of any candidate on this ballot. He raised $4,203,207, of which $2,280,977 came from individuals.
Strengths
Thirteen career laws is the strongest legislative record anywhere on this ballot, built on 27 years of committee seniority.
Trade-offs
Roughly two-fifths of his funding came from PACs and committees; and he led the primary with 41.0%, short of a majority.
Keep in mind
Long tenure is both accumulated influence and a long time for one district to be represented by one person.
Eric Jones
Democrat, who advanced with 22.2% of the June vote. He raised $8,378,929 — the largest campaign in this contest — of which $5,364,133 is his own money and $3,007,229 came from individuals. He has not served in the California Legislature or U.S. Congress.
Strengths
More than $3 million raised from individuals alongside his own contribution, a substantial base for a first-time candidate.
Trade-offs
Roughly two-thirds of his campaign is self-financed, and he finished 19 points behind despite outspending the incumbent.
Keep in mind
Money at this scale did not move the primary, which is a fact about this district worth carrying into November.
