The California Governor’s Race Could Help Sink the Billionaire Tax

California’s titans are gearing up for what’s sure to be an outrageously expensive clash over a proposed wealth tax on residents worth more than $1.1 billion. Supporters say they have more than enough signatures to put their ballot measure before voters in November; opponents say they do too for two measures that would override it. Tens of millions of dollars have already been spent on various campaigns, with some of the most eye-popping sums coming from tech founders, such as Google’s Sergey Brin.

But whether California’s wealthiest residents end up having to fork over more of their money to state government likely won’t just come down to what happens at the polls this fall. It could also be determined by which two candidates emerge from next month’s primary election for governor.
