The state Democratic Committee released a plan for unity on Monday in the state Senate between the mainline conference in the chamber and eight-member Independent Democratic Conference.

The plan, signed onto by the state party chairman and Buffalo Mayor Byron Brown, Vice Chairwoman Christine Quinn, Rep. Joe Crowley of Queens and union leader Hector Figueroa of 32BJ, is based on filling the soon-to-be-vacant seats in the Senate.

The proposal appears to be the latest effort by Gov. Andrew Cuomo to show his public intent at uniting Democrats in the Senate, a fractious chamber that has become an increasingly sore point for liberal activists in New York that was heightened in the wake of President Trump’s election.

The special elections, likely to be called after the budget is approved in late March or April, would would have both sides “pledge to come together to win” those races. One is a safe Democratic seat in the Bronx and other is a district in Westchester County that has been in the cross hairs of Republicans to little avail in the last decade.

“Upon winning, the IDC and Senate Democrats reunify as co-leaders,” the letter sent by state Democratic Committee Executive Director Geoff Berman states.

The letter paints a potential plan that would allow the leaders — Sen. Jeff Klein of the IDC and Sen. Andrea Stewart-Cousins of the mainline conference — to choose each others’ deputies and have approval over which bills come to the floor for a vote.

Both would have to disarm their political efforts at winning primaries against IDC or non-IDC candidates. The final chess piece — Sen. Simcha Felder, a Brooklyn Democrat who conferences with the Senate GOP — would presumably switch to the Democratic side and give the party 32 members.

“Having heard each side out many times over the past several years, we believe there is pathway to unification based on certain parameters that members on both sides have privately expressed a willingness to support,” the letter states.

“This solution is both reasonable, and, if the parties act in good faith, it would resolve the ongoing distrust and ensure a lasting peace and long term working relationship.”

The penalties for not agreeing would include the “infrastructure” of the state Democratic Committee uniting to primary IDC members or, for Stewart-Cousins, Democrats being pushed to replace her as leader.

Stewart-Cousins in a statement released minutes after Berman’s email backed an agreement that is “consistent” with the plan outlined in the proposal.

“Our conference has long called for all Senators elected as Democrats to work together and not empower the Republican minority,” she said.

“We continue to stand firmly in that posture as we seek a coalition under similar terms as have existed between the IDC and Senate Republicans, and are willing to enter a coalition consistent with the recent correspondence from state Democratic party officials. There is too much at stake for New Yorkers to wait any longer for their wishes to be fulfilled.”

Unity pledges in the Senate have been difficult to come by in recent years. The IDC was formed in 2011 after Democrats concluded a two-year and largely hapless stint in the majority.

In the period since then, the IDC has grown from its original four members to eight, with each borough of New York City represented currently in the conference.

The IDC was briefly in a power-sharing arrangement for a term with Senate Republicans that gave Klein and then-Majority Leader Dean Skelos, the power of co-president. Republicans won an outright governing majority in the 2014 elections.

But Klein has remained a key lawmaker in the state Senate and has been included in the budget talks with Cuomo, Assembly Speaker Carl Heastie and the now-Senate Majority Leader John Flanagan.

Updated: Klein responded to the proposal in a statement.

“This is a very exciting development. Since its very inception the IDC has worked to move the Senate out of dysfunction to advance progressive policies. We are ready to move forward, provided any final agreement between Democrats is based on the legislative agenda that we put forth on May 22, which includes: the Reproductive Health Act, the DREAM Act, GENDA, protecting Title X funding, public campaign finance, single-payer health care and the Comprehensive Contraceptive Coverage Act.

“We are eager and ready to be part of a Democratic Coalition that could proudly and publicly state what its legislative positions are going into the 2018 session. There is no reason for the special elections to be held up and I suggest they be held as soon as the law permits.”

Berman, in response, questioned how far the statement went.

“Let’s be clear: Is that a yes or a no? Do you accept the terms spelled out in the letter today from New York State Democratic Party leadership?” Berman posted on Twitter.
