Calling themselves the Fair Elections for New York campaign, they've launched a two-week, $815,000 media campaign statewide with 30-second television ads saying political races "are dominated by big money."
Groups funding the initial campaign include the Working Families Party, Citizen Action of New York, Friends of Democracy, the Public Campaign Action Fund and investor and activist Sean Eldridge.
A campaign spokesman says Monday they're working with Cuomo's staff and he joined a recent conference call to supporters.
Cuomo has proposed reducing maximum contributions, requiring prompt public disclosure of contributions and voluntary public financing of campaigns.
His own campaign fund shows nearly $22.5 million on hand from traditional fundraising.
