Backers of a new initiative don't want to wait. They are hoping to place the issue before the voters again next November.
They will need several hundred thousand signatures to qualify for the ballot.
"This effort is going back to those same voters and saying, 'Look, marriage equality is important, we think it's important you have another vote on it, please support marriage equality,'" said Mario Guerrero, Love Honor Cherish.
The initiative would redefine marriage as a union between two persons, regardless of sex, gender or sexual orientation.
