A coalition of groups on Monday urged the state Board of Elections to prohibit the practice of allowing individual donors to give unlimited campaign contributions through a network of limited liability corporations.

The coalition — composed of Citizen Action, the Working Families, Common Cause of New York and Every Voice, is asking the Board of Elections commissioners to re-write the regulation that created the so-called “LLC loophole” in the state’s campaign finance regulations.

“If we’re ever going to end Albany’s culture of corruption, we need to stop letting billionaires secretly dump millions into campaigns,” said Karen Scharff, Executive Director of Citizen Action of New York. “The Board of Elections must rein in this flood of cash now as a first step toward returning New York State government to voters.”

The call comes after the Brennan Center for Justice released a letter last week urging the Board of Elections to do the same.

The groups are renewing their emphasis on the LLC loophole after a budget agreement last month included new restrictions on the use of campaign funds as well as new reporting requirements for independent expenditure groups.

But the LLC loophole — long a source of derision for critics of the state’s campaign laws — was not addressed.

The groups pushing today for the closure of the loophole have also been full-throated in their support for the public financing of political campaigns. Last year, a year-long public financing program for the state comptroller’s race was created in the budget.

This year, with Senate Republicans fully in control of the chamber, a public financing system was barely discussed in the campaign finance reform debate.
