Putting the Pedal to the Metal on the Road to Cuckoo-Town

Just what you'd expect from the Kalifornia People's Socialist Republik:

In his 2018 bid for governor of California, Democratic Lt. Gov. Gavin Newsom told the the Sacramento Bee he'll propose a universal healthcare system for the state, a response to ongoing efforts by President Trump and the Republican-led Congress to replace the Affordable Care Act.

You can see that, currently, "health and human services" already takes about 30% of our state budget--the largest share, even larger than K-12 education.  How much more would a single-payer health care system cost, and where would the money come from?  Those things don't matter, as we'll no doubt pay not in dollars but in unicorn farts and pixie dust.
