SACRAMENTO– California’s top election official says supporters can start collecting signatures for a proposed ballot measure to strike the word “marriage” from all state laws. Supporters of this ballot measure want to replace it with the term “domestic partnership,” while keeping all the rights of marriage in place. The proposal is in response to a voter-approved gay marriage ban that passed in November. The new measure would repeal the ban, and define domestic partnerships as unions between all couples, regardless of sexual orientation. Secretary of State Debra Bowen said Tuesday that supporters must gather nearly 700,000 signatures by early August to get the initiative on the ballot.The measure is the grassroots effort of two heterosexual college students.
