THE HILL: Sanders, Clinton fight for green vote in tight Calif. race.

Bernie Sanders and Hillary Clinton are both hoping green voters will put them over the top as they near the end of a tight California primary fight.

Clinton this week locked up two key endorsements — from an environmental group and Gov. Jerry Brown (D) — both thanks to her positions on environmental issues.

Sanders, meanwhile, is taking his environmental message directly to California voters. He’s endorsed local efforts to block new fracking operations, an issue where he argues Clinton is weak, and pushed her on other initiatives dear to greens.

“I urge Secretary Clinton to be bolder,” Sanders said at a climate change press conference on Thursday.

“Of course she recognizes the reality of climate change, but I want her to join me in supporting a tax on carbon. I want her to change her views on the very important issue of fracking.”

Polls show a near dead-heat between Clinton and Sanders in California, the biggest prize on the Democratic primary calendar with 475 delegates up for grabs. It’s a critical state for Sanders’ hope of winning the nomination.

Sanders needs a good result in the state to help make the case to uncommitted superdelegates ahead of the July convention.

It would help.
