The Voting News has the release here, but basically from what I can gather, Secretary of State, Debra Brown says the state won't be meet the legal standards it set for itself in time to implement same day registration by 2014, which (again from what I can tell) the Secretary of State was responsible for:
"The law was expected to take effect in 2014. However, to be operative for the 2014 general election, the Secretary of State needed to complete its HAVA compliance by December 31, 2013. Last month, Bowen took to Twitter to explain why the state won’t be adopting California’s landmark same-day voter registration law anytime soon. 'That law (CA Elections Code section 2170) will likely take effect in 2016 or later,' Bowen tweeted on Jan. 13."So you know, there's that.
