Proposition 25 is a referendum on a law to replace California's cash bail system with risk assessments.
California is sticking with its traditional cash bail system, rejecting a nation-leading move to rely instead on risk assessments to decide which suspects should remain jailed awaiting trial.
With more than 11 million votes counted as of Wednesday, Proposition 25 had just 45% support.
The measure would confirm and put into effect a law that was passed two years ago that sought to make California the first state to eliminate cash bail for jailed suspects awaiting trial.
Gov. Jerry Brown signed SB10 in 2018 -- but the law was challenged so it hasn't taken effect.
