California voters rejected Proposition 40, a one-time 5% tax on the wealth of the state's billionaires. The Associated Press called the race Monday night.
53.8% voted no with 83% of votes counted, per the AP.
90% of revenue would have gone to healthcare programs.
$100 billion is what backers said the tax could raise.
$132 million or more came from Google co-founder Sergey Brin to oppose it.
Why it matters: The vote tested whether a state can tax accumulated wealth instead of income. Backers pitched it as a blueprint for other states and federal policy.
Opponents outspent supporters 250 to 1 on ads in late October, per AdImpact.
The measure split Democrats, including Newsom and Sen. Bernie Sanders.
