Campaign finance data is public — but it’s scattered across multiple filing systems, counties, and the FEC. Tracking who has raised what (and when) often means jumping between different databases and PDFs.
Below is a snapshot of the key 2026 primary races around San Diego County.
For many local and all state races across California, The Ballot Book centralizes campaign finance and election data in one place — making it easy to compare candidates side by side without chasing filings across systems.
The race for the 5th Supervisor District will be among the most watched. Due to some heavy early fundraising by John Franklin (not all of which appears in this table), he's grown a sizeable cash on hand lead among his two opponents.
With two open seats on the City Council, fundraising has been notable. Subscribers to The Ballot Book can access full San Diego campaign finance data, including filings, independent expenditures, and detailed committee activity.
Note: Jose Preciado's 2026 committee is a continuation of his 2022 committee, which explains why the receipts and expenditures are relatively high. Subscribers to The Ballot Book can access full Chula Vista campaign finance data, including filings, independent expenditures, and detailed committee activity.
The 48th Congressional district under the new lines is San Diego's most competitive Congressional district. Subscribers to the ballot book can view detailed election, registration, and census data for the new 48th Congressional district.
Finally, the 40th Senate District race to replace incumbent Senator Brian Jones is a competitive one. Subscribers to The Ballot Book can view detailed election, registration, and census data for the district, as well as detailed campaign finance data for the race.
