DISPATCHES FROM THE BLUE ZONES: Google cofounder Sergey Brin has now spent $100 million to fight California’s proposed billionaire tax—he could owe $13 billion if he loses.

According to a filing from Friday, Brin donated an additional $20 million to Building a Better California, a PAC and political advocacy organization opposing the state’s billionaire tax and supporting other pro-business policies and housing and infrastructure affordability. He has now given a total of $102 million to the group.

Proposition 40, which will be on the ballot in November, would impose a one-time, 5% tax on California’s 200 billionaires, with 90% of the revenue from the proposed measure going toward the state’s health care program and 10% going toward education, food assistance, and administration. Brin, with a net worth of nearly $270 billion, could owe more than $13 billion as a result of the tax.

Democrats want a national billionaire tax (that will mysteriously end up applying to far lesser beings) on the national level in the hopes that there will be nowhere to hide from it.
