Nearly 150,000 mail-in ballots are rejected in California’s June primary, according to reporting that cites the scale as higher than in recent statewide primaries. The rejection count comes as California continues efforts to expand access to voting and to count every ballot, including by processing vote-by-mail submissions through the state’s election systems. Multiple outlets describe the number as unusually large and note that it reflects ongoing issues in how ballots are accepted or disqualified under state requirements. While the reporting emphasizes that California is working to make voting easier and to improve ballot counting, it also highlights that a significant portion of mail ballots do not meet standards needed to be counted. The sources characterize the total as approaching 150,000 and frame it as a substantial increase compared with prior recent elections. The accounts do not indicate a single cause in the provided excerpts, but they collectively point to the rejection total as a major feature of the primary’s vote-by-mail results.
