Review note: Fontana United -- coalition campaign site naming a coordinated 5-candidate slate across this cycle's Fontana races: Joz Sida (Mayor), Nubia Diaz (Council District 1), Ben Vasquez (Council District 4), Joe Alvanez (City Clerk), and Kamal Namou (City Treasurer); self-describes as "an inclusive alternative" to incumbent leadership with a shared platform opposing warehouse expansion, backing evening meeting times and language access, and supporting police accountability and opposing "federal immigration abuses" may have more bias because it is an advocacy voter guide compared to other formal government and nonprofit journalism sources.

netfile.com (opens in a new tab)City of Fontana's own NetFile-hosted public campaign-finance portal (agency code FTA, netfile.com/public/FTA), linked directly from the city's own "Campaign Finance Disclosure Statements" page (fontanaca.gov/3515) as public.netfile.com/pub2/?aid=FTA; queried directly by name for all seventeen 2026 candidates via the portal's own name-search and transaction-search tools. Jackie Heredia, Sal Casillas, Mylinda Carrillo, Nicholas Ortega, and Lourdes Goñi Garcia (Mayor) and Daniel Quiroga (City Clerk) have no filer of any kind registered with this portal. Benjamin "Ben" Vasquez Jr. (Council District 4) and Nubia Diaz (Council District 1) have each filed only Form 410/501 committee-registration paperwork, with no Form 460 or itemized transaction on record for either. Incumbent Mayor Acquanetta Warren's committee filed a semi-annual Form 460 for January-June 2026 (amended August 19) and has since filed six Form 497 late-contribution reports; itemized transactions include $2,000 from the California Real Estate PAC, $2,000 from retiree Noel Dunn, and $1,000 from Fontana developer/owner Rima Tahan, against expenditures including $1,700 (twice) to web consultant Blake Burum, $1,061.37 (twice) in online-fundraising-platform fees to Anedot, and $510.56 (twice) in literature costs to Minuteman Press; her committee has also made its own contributions this cycle to other local candidates' committees, including $1,087.50 apiece to Joe Armendarez's City Treasurer committee and Germaine Key's City Clerk committee (both reported in late August/early September 2026), plus contributions to a water-district and a school-board candidate. Jocelyn "Joz" Sida's committee filed a semi-annual Form 460 for January-June 2026 (August 10) plus a late-contribution report; itemized contributions include $3,621 aggregated through the ActBlue online platform, $2,000 from Nathan Schanfein (a project engineer at a local magnetics manufacturer), and $100 from Dan Silver, executive director of the Endangered Habitats League. Phillip Cothran's committee filed a semi-annual Form 460 for January-June 2026 (July 15) and has since filed five late-contribution reports in August 2026 alone totaling $15,600 -- $5,900 from the San Bernardino County Professional Firefighters Local 935 PAC and $2,500-$2,600 each from four logistics/construction businesses (Lord Constructors Inc, Naksas Enterprise LLC, Optimum Logistics Inc, South Start Logistics Inc) and a retiree, Ralph Thrasher. Luz Perez's committee (active since August 2025, despite her own campaign website not rendering readable text in this pass) filed a semi-annual Form 460 for January-June 2026 (July 31); itemized contributions are almost entirely small-dollar, $50-$250 gifts from individual Inland Empire donors (a registered nurse, a teacher, a union organizer, several self-employed workers), plus a $2,500 contribution from a state Assembly candidate's own committee (Juan Carrillo for Assembly 2026) and $686.41 in ActBlue processing fees. John B. Roberts's committee (active since at least 2020) shows a January-June 2026 contribution of $500 from Southern California Edison and $1,500 from a local teacher, Joseph Montalvo II, alongside a recurring pattern of several-hundred-to-several-thousand-dollar sponsorships paid from the committee to local community organizations and events (the Miss Fontana Pageant, Cherish Ministry, Working Dogs for Warriors, the Rescue Task Force, Fontana Middle School) going back multiple cycles. Germaine Key's committee filed a semi-annual Form 460 for January-June 2026 (July 15) and received a $1,087.50 contribution from Mayor Warren's committee in late August 2026. Joe Alvanez has filed only a Form 501 candidate intention statement (July 15, 2026), with no committee or itemized financial activity on record. Kamal Namou's committee filed a Form 410 (July 13) and a Form 501 (May 18), and has since filed a Form 497LCR late-contribution report (August 5, 2026) confirming at least one contribution of $1,000 or more, though the specific amount was not available through the portal's transaction search as of this retrieval. Joe Armendarez has run for local office repeatedly and been well-funded in the past -- a 2024 City Council campaign (its committee since renamed "Joe Armendarez for City Council 2028") raised well over $60,000, including a $13,600 loan from Protect Our County PAC and five-figure spending with a Rancho Cucamonga print shop -- and a City Treasurer-specific committee, "Armendarez for City Treasurer 2026," is confirmed active (it received the $1,087.50 contribution from Mayor Warren's committee noted above), but this dataset could not locate that committee's own filing history or itemized contributions separately from his older, differently named committees in the time available for this pass.
