As yet another poll shows Gov. Andrew Cuomo’s re-election margin being hurt by a liberal Working Families Party candidate, Assembly Speaker Sheldon Silver said the party can’t expect the governor to win on every legislative issue.

“I think they have no choice,” Silver said this morning at a breakfast for Comptroller Tom DiNapoli. “He’s been right on the issues. He’s had the progressive issues. He can’t succeed on everything. The only thing with them – he’s a victim of his success.”

Indeed, Cuomo himself has pointed to a raft of socially liberal measures he’s achieved since taking office in 2011, including the legalization of same-sex marriage and a sweeping gun control measure approved last year.

Still, the labor-backed Working Families Party remains restive over the governor’s fiscal agenda.

The WFP has not ruled out granting its ballot line to another candidate, and have been pushing Cuomo in recent weeks to have state lawmakers pass a broader public financing system than what was approved in the state budget in March.

Silver added that a stand-alone WFP candidacy would only help Cuomo’s GOP opponent, Rob Astorino.

“He has tried. Believe me, I’ve been at meetings where he has tried to get public financing,” Silver said. “You don’t throw out someone good for someone who might be perfect.”

Silver was not bullish on the chances of a broader public financing measure passing by the end of the legislative session in June.

“I don’t see it,” Silver said, citing Republican opposition to the proposal.
