“California Gov. Gavin Newsom on Friday proposed a national tax on billionaires that he says is the first part of an “economic reset for America” agenda, which aides explicitly say is part of his considering to launch a presidential campaign,” CNN reports.Said Newsom: “The system America’s founders built was designed to prevent the concentration of power in a few hands, but we have allowed that concentration to happen anyway, slowly, in plain sight, over decades. We can reverse it together, as a country.”“It is extremely early in the presidential campaign cycle for a policy proposal — but comes as Democrats continue to embrace economic populism and moves against the wealthy. It also comes as California voters in November will decide on a billionaires’ tax after the governor and opponents of the tax late Thursday failed to reach a deal to keep it off the ballot.”Wall Street Journal: California’s proposed billionaire tax will appear before voters in November, teeing up a high-stakes fight among Democrats.
