California Donor Table

LOS ANGELES — Nearly 150,000 California voters had their mail-in ballots rejected for the state’s June primary, a spike from recent elections even as the state attempts to make voting easier with the goal of boosting participation and counting every ballot.

The GOP backers of a sweeping voter ID measure set to appear on California’s ballot in November are suing state officials for slightly altering the proposal’s language for voters.

Latino voters were one of the biggest swing voting blocs in last month’s Prop. 50 special election, which some political observers say represents a bellwether for President Trump’s waning support among California’s largest demographic group.
