A progressive advocacy group on Wednesday endorsed Cynthia Nixon’s bid in the Democratic primary race for governor.

The group Democracy for America, founded by former Vermont Gov. Howard Dean, called Nixon “the real progressive in the race” for governor.

“For 17 years, Cynthia Nixon has been a leading voice and on-the-ground fighter for public education, women’s rights, LGBTQ equality, and protecting New York’s environment from corporate polluters,” said the group’s executive director, Charles Chamberlain.

“Cynthia has brought that same unrelenting zeal for bold ideas and bottom-up change to the race for Governor. With Cynthia Nixon, the proudly progressive state of New York finally has the chance to have a governor in Albany who shares their values in the battle for racial and economic justice –and DFA members across the state and nationwide will stand side by side with her in this fight.”

Dean left the group in 2005 after he became chair of the Democratic National Committee.

“I am very grateful to receive this endorsement from Democracy for America,” Nixon said. “DFA knows that campaigns are built from the bottom-up — through grassroots canvassing, phone-banking, and fundraising. I am excited to work with DFA in building a progressive movement here in New York.”

Cuomo has bristled at implications his progressive bona fides don’t stack up and his supporters have pointed to a raft of accomplishments during his time as governor, including the passage of a minimum wage hike that eventually grows to $15 in the coming years in the New York City area, paid family leave, a sweeping gun control law, the legalization of same-sex marriage and regulations that bolster the rights of transgender New Yorkers.

Still, progressives have faulted Cuomo for compromises with Republicans in the state Senate, who they say have been allowed to remain in power by Cuomo.

Over the last several months, Cuomo has made efforts on behalf of Democrats to help them gain power in the Senate, including brokering a unity deal that led to the dissolution of the Independent Democratic Conference and pledges to help elect Democrats in key races.
