California went down this road before, and turned back. The last presidential election, in 2012, featured a vote to repeal the death penalty in the state.
Proposition 34 went down to defeat, though narrowly. Now another death penalty repeal appears on the ballot, as Proposition 62.
Whatever its number, it will get no support from San Bernardino County D.A. Mike Ramos. He advocates keeping capital punishment in place, and supports a different measure, Prop 66, which would keep the death penalty and tweak the law.
Meanwhile the Yes on 62 campaign is working to get its measure across the finish line.
