Proponents of Proposition 70 argue that forcing a two-thirds legislative vote ensures money is spent wisely for high-priority programs that benefit all Californians and that it is not diverted for pet projects.


Opponents of Proposition 70 claim that it grew out of an oil industry-backed effort to weaken the state’s premier program to curb harmful air pollution and climate change. They say it will increase legislative gridlock, hurt public health, and empower anti-environmental special interests.
