A record 19.4 million Californians are registered to vote in today's general election, up from 18.2 million in 2012, according to the office of California Secretary of State Alex Padilla.
More than 78% of eligible Californians are registered, Padilla said.
"This also represents the highest percentage of eligible California citizens registered to vote heading into a general election in 20 years," Padilla said.
"Our office has partnered with local elections officials, businesses, community groups and even professional sports teams throughout California to help a record number of Californians register to vote," Padilla said.
Over 8.7 million voters registered as Democrats, constituting 44.9% of registered voters in the state, up from 43.7% in 2012.
More than 5 million voters registered Republican, or 26% of voters, down from 29.4% in 2012.
Over 4.7 million California voters registered with no party preference, or 24% of voters. In 2012, fewer than 21% of voters registered with no party preference.
Almost 20% of registered voters are over 65. Fewer than 14% of registered voters are under 25.
"Reminders from social media networks and the popularity of online voter registration also helped fuel this year's voter registration surge,"
