Nearly 200,000 Californians registered to vote online in a two-day period after a reminder was posted on Facebook the Secretary of State’s office said in a news release on Thursday, May 19.

California Secretary of State Alex Padilla reported that the spike in registrations on the California Secretary of State’s online voter registration website on Monday and Tuesday of this week coincided with a new Facebook effort to facilitate voter registration in California.

On Monday, Californians who logged into their Facebook accounts began receiving a reminder to register to vote through a link appearing at the top of their News Feed.

The results were stunning according to the release.

“Monday’s registration activity was the second highest in the nearly four year history of California’s online voter registration site,” said Padilla. “We appreciate Facebook’s commitment to increasing voter registration in our state. The power of social media to connect Californians to online voter registration was on full display,” he said.

On Monday, 143,255 registrations or updates of registration information took place on the Secretary of State’s online voter registration site. On Tuesday, another 56,717 registrations or updates of registration information were completed through the voter registration website according to the release.

The online activity showed that approximately 33.55% of these transactions were completed by Californians ages 17-25. And, about 29.23% of these transactions were completed by Californians ages 26-35.

May 23 is the deadline to register for the June 7, 2016 Presidential Primary Election.

“Whether you’re registering for the first time or you just need to update your registration information, you can do it online at RegisterToVote.ca.gov” Padilla said.
