The Working Families Party is scheduled to hold its convention on Saturday in Harlem, with plans to pick an attorney general candidate.

But who the candidate will ultimately wind up being remains up in the air as the party could select a placeholder for the post after New York City Public Advocate Tish James confirmed she would not seek the party’s line in her bid for AG.

The endorsement could also go to James’s likely Democratic rival for the party’s nomination, Zepyhr Teachout, a Fordham Law School professor who ran for governor in 2014 and a Hudson Valley House seat in 2016.

For now, party officials are not committing to either Teachout’s candidacy or the placeholder who could be swapped out for the eventual winner of the Democratic primary.

Teachout has been an ally of gubernatorial candidate Cynthia Nixon and is serving as her campaign treasurer.

Nixon’s bid for the Democratic gubernatorial nomination against incumbent Andrew Cuomo has been buoyed last month by the WFP’s endorsement.
