Spending and opposition
The “no” side raised roughly 10 times as much as the “yes” side. Google co-founder Sergey Brin alone dumped more than $100 million into a political action committee working to defeat the measure. Billionaires donated millions of dollars to a political action committee, Building a Better California, working to defeat the measure. The committee, which backed other measures on the ballot designed to nullify the tax, raised more than $333 million, nearly a third of which came from Brin.
Some traditional Democratic allies, including Planned Parenthood and the California Medical Association, were part of a coalition opposing it. They were concerned about how the tax revenue would be divvied up and about the potential impact on the state’s budget if there was a mass exodus of wealthy taxpayers. California’s budget relies heavily on the income tax of the state’s richest residents.
“Proposition 40 was a reckless experiment conducted on our state’s economy with little regard for the harms it would cause,” the coalition said in a statement.
