CA prop 38 is a scam - vote NO. For example see: This CA proposition will send $4 billion to a single nonprofit. Who’s behind it? calmatters.org/politics/ele...
calmatters.org
Is this proposition a $4 billion giveaway to a billionaire’s LA research center?
Proposition 38 will award $4 billion to one unnamed research center. Under the very specific criteria, only one center seemingly qualifies.

Science has more than doubled our life expectancy, revolutionized our quality of life, and powered unprecedented technological advancement. But can we afford to take scientific progress for granted? What happens when science funding is slashed, diversity is suppressed, and pseudoscience takes hold?
