Filing documents for the Working Families Party’s backing of Gov. Andrew Cuomo are yet to be delivered to the Board of Elections, officials there confirmed Monday.

In contrast, the state Conservative Party’s designating certificates were filed this morning backing the full Republican slate for Row C: Rob Astorino for governor, John Cahill for attorney general and Bob Antonacci for state comptroller.

Both the WFP and the state Conservative Party held their nominating conventions over the weekend.

While Cuomo was challenged for the labor-backed party’s endorsement by Fordham Law professor Zephyr Teachout, the incumbent Democratic candidate ultimately secured the WFP’s backing for re-election.

Last month, Cuomo received the endorsement of the state Independence Party after pre-signing documentation accepting the line. He told reporters before the receiving the endorsement but after signing the paperwork he would address the IP endorsement “down the road.”

Cuomo later clarified that he signed a “batch of paperwork” expecting to not be available to sign it should he have gotten the endorsement.
