California voters will decide in November on ballot measures, including Proposition 40, that would impose a one-time tax on billionaires in the state. More than $200 million has been spent by groups supporting and opposing the measure, with additional spending expected before the election. Google co-founder Sergey Brin has contributed more than $100 million to a group working to defeat the tax, according to One America News. A poll cited by NBC News found 48% of voters support the measure and 38% oppose it, short of a clear majority. The Center Square reports that economists have noted Proposition 42, also on the ballot, could cancel out the effects of Proposition 40 if both pass.
