Silicon Valley's elite is on edge awaiting results for California's Prop. 40 billionaire tax

Californians are voting on a proposal that could send a one-time, huge tax bill to the state's billionaires.

Early results give the "No" vote a commanding lead among both Silicon Valley elites and rural Hispanic counties. It could bring in $100 billion to plug a coming Medicare hole — or lose billions in tax revenue. The morning after the midterms, there's still no answer on California's billionaire wealth tax — and the final results may not be in for days or even weeks. As of around 10:30 a.m. Eastern time Wednesday, 44.4% of California voters had thrown their support behind Proposition 40, which would impose a one-time "5% tax on certain taxpayers with assets over $1 billion." With about 60% of the vote in thus far, there's still plenty of time for the results to reverse, but the "No" vote has a commanding lead. More interesting is how support and opposition have played out across the Golden State. The socially-progressive urban strongholds of Los Angeles, San Francisco, and Alameda County (home to Berkeley and Oakland) are favoring the measure with slim majorities. Meanwhile, many of the poorer and majority-Hispanic agricultural communities in California's Central Valley and desert regions have come out against the wealth tax by double-digit margins. Rural California has an unusual bedfellow in wealthy Silicon Valley.
