An advocacy group pushing for the creation of a public campaign financing program on Wednesday launched an effort to boost the issue with state lawmakers, having supporters make phone calls and text messages to members of the state Senate and Assembly.

The calls are being organized by Stand Up America, a member of the broader Fair Elections coalition that’s called for the passage of public financing this year.

“We have until April 1st to get campaign finance reform in the final NY budget,” the group wrote in an email to supporters. “Wealthy special interests will no doubt spend the next eleven days trying their hardest to convince our representatives they need big-money donors more than they need us, their constituents.”

The call campaign came as Democrats in the Senate held a public hearing on the issue.

But the Democratic-controlled Assembly is viewed as the main battleground for public financing. Assembly Speaker Carl Heastie on Wednesday after a meeting with Gov. Andrew Cuomo and Senate Majority Leader Andrea Stewart-Cousins said some lawmakers remained concerned about the effect independent expenditure committees could play in a public financing system.
