From the Morning Memo:

New York Republican Chairman Nick Langworthy did not rule out on Monday backing a registered Democrat in the race for Queens district attorney, but said the issue was ultimately up to the local party committee.

A recount is underway in the extraordinarily close Democratic primary race between Melinda Katz and Tiffany Cabán, with a legal challenge that could drag on for weeks amid affidavit ballot reviews.

A Cabán victory has spurred talk of Republicans in Queens backing a registered Democrat for the post — a not-unheard-of-move, including in statewide races and in areas where Democrats easily outnumber Republicans.

Just last year, Republicans backed Jonathan Trichter for state comptroller who launched his campaign while still a registered Democratic voter.

Republican candidate Daniel Kogan last month raised the possibility of not running against Cabán.

Katz, the Queens borough president who has the backing of establishment Democrats, has ruled out running on the Republican line.

Langworthy, who has pledged to re-invigorate the New York Republican Party, said it it’s understandable GOP officials would eye a wider array of candidates, which could entice middle-of-the-road voters.

“In places where you are very outgunned in terms of enrollment, sometimes you have to get creative to make a difference in the race,” Langworthy told reporters during a stop at the Capitol on Monday.

But he also noted no decision on who runs under the GOP banner will come soon, given the lengthy court battle underway on the Democratic side.

“We’re going to have a long haul there, but I do think the Republican Party in Queens is leaving just about everything on the table to discuss how to make the best difference they can,” Langworthy said. “They want to give voters a choice in that election. I think it’s critically important we have elections right up to November; things aren’t settled on primary day.”
