From the Morning Memo:

A coalition of progressive groups in New York City is organizing an effort to avoid having former Sen. Bill Perkins’s open seat go to a candidate who would join the Independent Democratic Conference.

The groups — including True Blue NY, Code Blue, Swing Left NY, Indivisible Harlem, Morningside Heights Resistance and All Hands on Deck NY and No IDC NY — plan to review candidates running for the seat and whether they would be potential recruits for the IDC.

“They suggest several ways to vet prospective candidates, including examining the candidates’ funding sources, considering previous contacts with IDC members, and asking about their personal beliefs concerning the role of the IDC in the Senate,” the groups said in a release.

Mindful to the coalition is the victory of Sen. Marisol Alcantara in last September’s primary to replace Adriano Espaillat, who is now a member of the House of Representatives. Alcantara was backed by the IDC and joined the conference when she took office this year.

Perkins won a special election last month to fill a vacant seat on the New York City Council. A special election to fill his Senate seat has been scheduled by Gov. Andrew Cuomo for May 23.
