Californians still support the concept of a bullet train from Los Angeles to San Francisco, but after months of troubling disclosures about the project’s cost and schedule, just 31% of voters across the state want to keep building it, according to a USC Dornsife/Los Angeles Times poll.

The survey confirmed what has been consistent in California public opinion for half a decade: The public has never abandoned its dream of a high-speed transportation system but rejects the rail authority’s performance in building it.
