Independent Democratic Conference

The Independent Democratic Conference (IDC) was a caucus consisting of several Democratic members of the New York State Senate that existed from 2011 to 2018. The IDC is notable for having formed a power-sharing arrangement with the Senate Republican Conference. At the time of its dissolution, the IDC had eight members: Jeff Klein, Marisol Alcantara, Tony Avella, David Carlucci, Jesse Hamilton, Jose Peralta, Diane Savino, and David Valesky. The IDC was led by Jeff Klein.

Klein, Savino, Valesky, and Carlucci formed the IDC in 2011 due to disagreements with John L. Sampson, the Democratic leader of the New York State Senate. The IDC allied itself with Senate Republicans throughout much of its existence. During the 2013–14 legislative session, the IDC and the Senate Republican Conference controlled the Senate jointly, as the Senate Republicans did not have sufficient numbers to form a governing majority on their own.

At the request of Democratic Governor Andrew Cuomo, who had previously supported the IDC, the IDC dissolved in April 2018. Following the IDC's dissolution, its members rejoined the Senate Democratic Conference and Klein became the Deputy Democratic Conference Leader. In the subsequent Democratic primaries in September 2018, six of the eight former IDC members were defeated; only Carlucci and Savino won their respective primary contests and were re-elected. Carlucci did not seek re-election in 2020, and Savino did not seek re-election in 2022.
