It garnered votes from Democrats, independents, and Republicans alike, as well as among Caucasians, African-Americans, Asian-Americans, and Latinos. Nearly 800,000 Californians signed petitions to place the measure on the ballot. HSUS was also a participant in a ballot initiative campaign focusing on inhumane treatment of farm animals in Ohio.
