Names ballot designations verbatim as filed: "Mayor, City of San Leandro" (González), "Business Operations Director" (Maes), "San Leandro Councilwoman" (Viveros-Walton), "Appointed City Councilmember" (Aguilar), "Nonprofit Executive Director" (Thomas), "Chief Plant Operator" (Trujillo), "San Leandro Councilmember" (Bowen). The system's own "Incumbent" field reads "N" for every San Leandro candidate, including sitting councilmembers -- this dataset does not treat that field as reliable for city races given San Leandro's own confirmation (see san-leandro-clerk-candidate-info-2026) that the district seats have no incumbent for filing purposes this cycle only because the district structure itself is new, not because no one currently holds the office.

southtechhosting.com (opens in a new tab)City of San Leandro's own Campaign Finance Disclosure Portal (a SouthTech eRetrieval system, southtechhosting.com/SanLeandroCity/CampaignDocsWebRetrieval), checked directly: it is a DevExpress ASPX web-forms grid application whose candidate-name search requires a stateful postback keyed to a per-session token generated by the page's own client-side JS, not a plain queryable API -- it was not practically retrievable by a direct fetch in this pass. Separately, NetFile's own public agency directory (netfile.com/api/public/sites/api/agencies) was queried directly and confirmed San Leandro has no entry under any agency code among all 729 listed agencies, so San Leandro's candidates are not using that platform either. No dollar figure is asserted for any San Leandro candidate as a result.

City of San Leandro

San Leandro City Council, District 2 (Short Term)

This person would hold San Leandro's District 2 seat on the 7-member City Council (six district members plus the mayor). They vote on city ordinances, the budget, and land use, under a council-manager government with an appointed City Manager. The term is four years. This is the first district-based election for this seat -- Measure F, passed at the city's June 2, 2026 special municipal election, converted Council elections from citywide (at-large) voting to single-member districts starting this cycle.

James Aguilar was appointed to the Council in April 2026. They drew no opponent for the rest of this term and are unopposed.

This person would hold San Leandro's District 2 seat on the 7-member City Council (six district members plus the mayor). They vote on city ordinances, the budget, and land use, under a council-manager government with an appointed City Manager. This is a short-term seat -- the winner serves only the balance of the current term before the seat returns to San Leandro's regular 4-year election cycle.

This is also the first district-based election for this seat: Measure F, passed at the city's June 2, 2026 special municipal election, converted Council elections from citywide (at-large) voting to single-member districts starting this cycle. Because the district itself is new, the city's own candidate-filing notice treats this office as having no "eligible incumbent" for filing-deadline purposes, even though a sitting councilmember (appointed to an at-large seat earlier this year) is running for it.
