The Working Families Party and the gubernatorial campaign of Cynthia Nixon mocked the endorsement of Gov. Andrew Cuomo by the Women’s Equality Party on Friday after the ballot line formed at his urging four years ago announced it would support him once again.

“We’d like to be the first to congratulate Andrew Cuomo on winning the highly-coveted endorsement of the Women’s Equality Party, a party he founded and funded,” said Cynthia for New York Senior Strategist Rebecca Katz. “We can’t help but wonder if Cuomo will run on his so-called Women’s Equality Party line against New York’s first female Democratic nominee Cynthia Nixon in the general election.”

The party was first formed in 2014 as a vehicle in part to boost the 10-point women’s agenda, a package of measures that aimed to bolster women’s rights in the workplace and housing, as well as crack down on domestic violence and human trafficking. The entirety of the package has become law, save for a plank that would codify the Roe v. Wade decision in state law.

The WEP has been an especially sore point for the Working Families Party, which is backing Nixon this year. WFP supporters have pointed out the similarities in the two parties’ initials and have considered it a rival ballot line meant to draw votes away from them in the general election.

“Unlike Cuomo, the Working Families Party has invested in building women’s power,” said WFP Co-Chair Karen Scharff.

“WFP has a long history of recruiting progressive women and helping them win — even when the Democratic Party machine tried to block their path. Tish James, Yuh-line Niou, Diana Richardson, Nily Rozic, Zephyr Teachout, Melissa Mark Viverito and many more, got critical support from the WFP, when the Democratic Party was happy with the establishment candidates.”

In a tweet, Cuomo spokesman Rich Azzopardi knocked WFP State Director Bill Lipton for worrying that the WEP would hurt his organization’s vote total and ballot states. Parties must have a 50,000-vote threshold to automatically qualify for ballot states.

“Translation: in it’s diminished state, #BossBill is freakin’ out about his ballot status,” he posted.
