Four years ago California voters overwhelmingly passed Proposition 30, the emergency ballot measure that Governor Jerry Brown and state education leaders had argued was needed to rescue public schools and community colleges from the fiscal free-fall of the 2008 Great Recession.

It also provides strong justification for a “Yes” vote on Prop. 55 that would maintain the initiative’s provisions. Read Part I of the Capital and Main series here.
