On the 2018 campaign trail to become California’s Democratic governor, Gavin Newsom signaled his support for a statewide single-payer health care system.

“I’m tired of politicians saying they support single-payer but that it’s too soon, too expensive or someone else’s problem,” Newsom said in a statement helping secure him the crucial support of the state’s powerful nurses union during a contentious gubernatorial primary.

Now, as California lawmakers once again get close to establishing such a program, all eyes are on Newsom to see how he will come down on the issue — and whether the millions he and his party received from health insurance industry donors will convince him to abandon the cause he previously touted.
