In 2012, Californians voted on Proposition 30, which raised taxes on the richest citizens in order to raise funding for public schools and charter schools. The measure passed, despite a well-funded effort to defeat it.

A group of unions and progressive activists released a list of nearly 80 wealthy Californians who secretly funded the campaign to defeat Proposition 30. One of them was billionaire Eli Broad, who publicly supported Prop 30 but donated either $500,000 or $1 million to the effort to defeat it.

The progressive activists–called California Hedge Clippers–dug into records to show where the money came from to fight the temporary tax to aid schools.

Individuals named in the group’s report include Silicon Valley tech and investment executive John H. Scully ($500,000), investor and Hyatt Hotel heir Anthony Pritzker ($100,000), developer Geoff Palmer ($100,000) and private equity investor Gerald Parsky ($50,000).

Donors, regulators concluded, contributed money to an out-of-state organization, which circulated funds through a series of other groups and eventually back to California. By then, the identity of the donors was beyond the reach of disclosure laws.

As the money was channeled to California, some transfers were not properly disclosed and therefore violated the law, officials said. Well after the election, a California investigation resulted in $16 million in fines to some of the groups as well as the disclosure of some donors, including Broad, who either gave $500,000 or $1 million, depending on how the source documents are interpreted. The donors were not fined….

Among the names to emerge in the California research is Nils Colin Lind ($50,000), who was at the time an executive at Blum Capital, the firm he co-founded with Richard Blum, California Sen. Dianne Feinstein’s husband. The larger contributions include $800,000 from machine-tool manufacturer Gene Haas. The researchers also uncovered additional money from the Fisher family, heirs to the Gap fortune and among the most generous supporters of charter schools; their revised total is $10 million.

The list also includes leaders of the charter school movement, such as Scully and Tony Ressler ($25,000), a former longtime board member of the charter group Alliance College-Ready Public Schools.

Like other public schools, charters reaped huge financial benefits from Proposition 30 after it passed in 2012. School officials across the state hope voters in the November election will extend the tax on the wealthiest 2% of earners….

The donors’ money traveled a circuitous path. They contributed to Americans for Job Security, a Virginia trade association. This outfit then passed the money to the Center to Protect Patient Rights in Arizona. The center next sent $11 million to a Phoenix group, Americans for Responsible Leadership, which provided it to the Small Business Action Committee. That committee spent the money on the California campaigns.

In another relay, the Center to Protect Patient Rights provided more than $4 million to the America Future Fund in Iowa, which passed the money to the California Future Fund for Free Markets, a campaign committee supporting Proposition 32.

Not all of the donated money made it back to California. About $10 million was captured by groups in other parts of the country, the researchers said.
