More than 250 protesters converged outside the East Hampton beachfront estate of hedge-fund billionaire Dan Loeb on July 11 as those inside dined at a $5,000-a-plate fundraiser for Gov. Andrew Cuomo.

With chants such as, “Hey, governor 1 percent, who do you represent?,” the demonstrators were protesting the outsized influence of the superrich on Cuomo’s policy agenda and, in particular, his pro-charter policies that disadvantage public schools. The host, Loeb, is the chairman of the board of Eva Moskowitz’s Success Academy charter school network and a longtime backer of Cuomo.

Marchers wore T-shirts emblazoned with the message: “Hedge funds = Inequality,” and in case they couldn’t be seen by those at the party, they made themselves heard with chants that included: “Cuomo, Cuomo, you can’t hide, we can see your greedy side!” Two small planes carrying banners with similar messages flew above the Loeb estate.

The demonstration was organized by Hedge Clippers, a coalition of labor and community activists dedicated to drawing attention to the influence of large, wealthy donors on elected officials who set public policy in education and other areas. Teachers and other community activists had boarded buses in the Bronx, Brooklyn, Manhattan and Hempstead, L.I., to attend the demonstration that began with a half-mile march from a church in Amagansett to the Loeb mansion.

The New York Post reported that Hamptonites were worried that the demonstration would scare aware donors just as the fundraising season in the wealthy Long Island enclave is beginning for presidential candidates.

The Hedge Clippers staged a similar protest in March at the Connecticut home of Paul Tudor Jones II, another billionaire political donor who supports charter school expansion at the expense of public schools.
