Notes

Three specific incidents documented: (1) Riverside County CA — Sheriff Bianco seized 650,000+ ballots in March 2026 based on election integrity group's claims later attributed to misuse of raw data; (2) Fulton County GA — FBI search warrant executed January 2026 on claims already debunked; (3) Maricopa County AZ — federal grand jury subpoenaed records in March 2026 connected to Arizona Senate partisan audit. Brennan Center frames as resource drain and confidence-undermining pattern.
