Since just before the last California presidential primary, the proportion of voters registered as Republicans has fallen from 33.5 percent to 30.4 percent, according to new figures from the California Secretary of State.
Democrats halted a steady, years-long decline with a one percentage-point bump in registration since the last primary, largely due to leftover gains from Obama's last campaign, the new figures show. About 43.6 percent of the state's voters are registered Democrat.
The number of decline-to-state voters continues to grow, but more slowly than it did a decade ago. More than one in five of the state's voters aren't registered with a party.
