A group of California Democratic leaders, including mayors Matt Mahan of San Jose and Bobbie Singh-Allen of Elk Grove, have announced their support for Proposition 36, a ballot measure aimed at increasing penalties for certain drug and theft crimes. This stance places them in opposition to Governor Gavin Newsom, who argues that the initiative will exacerbate prison overcrowding and cost the state billions. The measure seeks to revise Proposition 47, which downgraded many nonviolent crimes to misdemeanors, by introducing stricter sentencing and mandated treatment for repeat offenders, particularly those involved with fentanyl. Proponents, including significant corporate donors like Walmart, argue that Prop 36 will reduce crime and promote rehabilitation, while critics fear it will undermine existing treatment programs funded by savings from Prop 47. The debate highlights a significant rift within the Democratic Party over criminal justice reform.
