Republicans in the state Senate on Tuesday criticized the commission determining how a system of publicly financed campaigns will work in New York as the Democratic Suffolk County executive pushed the panel to curtail fusion voting in the state.

The commission met on Long Island on Tuesday as it prepares a final report laying down the specifics of how public campaign financing will work in New York. Lawmakers can either allow the recommendations to stand and have the force of law or return by the end of the year and vote to change it.

But Republicans have taken issue with the commission’s creation and the process being used to create public financing.

“Democrats, who control every aspect of state government, unconstitutionally forfeited their law-making duties to a group of unelected appointees who sit on the Campaign Finance Reform and Election Commission,” said Senate Minority Leader John Flanagan. “I refuse to testify before this traveling Commission of Scapegoats, who are unaccountable to the public and while I have a pending cross claim against this unconstitutional action.”

Legislation-by-commission is not unheard of in Albany.

Only last year, with Republicans in the majority, lawmakers and Gov. Andrew Cuomo agreed to the creation of a commission that determined a phased-in pay raise for lawmakers, which also capped the amount of money lawmakers can earn in the private sector. The outside income cap was later struck down in court challenges.

But Republican lawmakers have had a long-standing opposition to publicly financed elections, arguing taxpayers should not be on the hook to fund political campaigns.

Senate GOP lawmakers this month joined a lawsuit backed by the Conservative Party challenging the commission.

“But the public should be aware that Democrats plan to allow others to write a $100 million welfare plan for their campaigns to bankroll expenses like nasty campaign commercials, annoying robocalls, and mailers,” Flanagan said. “Democrats also intend through this Commission to unconstitutionally take away voter choice by eliminating fusion voting.”

Meanwhile, at the panel’s hearing itself, Suffolk County Executive Steve Bellone urged the commission to end the practice of fusion voting, which allows candidates to run on multiple ballot lines.

As he has done before, Bellone pointed to the corruption case of former Suffolk County District Attorney Thomas Spota and local Conservative Party Chairman Ed Walsh. Spota had run on the local Conservative line.

“It is time to fundamentally restructure our election law in this state to meet the times, to fully implement criminal justice reform, and to usher in a new era of accountability, fairness and transparency,” Bellone said. “The state has made great progress in bringing New York’s elections laws into the 21st century but you must complete the job.”
