A District Leader is an elected, volunteer position within the Democratic Party in New York. Each Assembly District has at least two Democratic leaders - a man and a woman - elected by the registered Democrats who live there. Most districts in New York City are further subdivided into parts; for instance, I am the District Leader for Part A of the 76th District (Roosevelt Island and Manhattan East of 3rd Avenue between 61st and 78th streets).
The District Leaders coordinate the party's functions in the district: arranging for poll workers to staff sites on election day, collecting signatures to get Democratic candidates on the ballot, communicating community needs to Democratic elected officials, organizing the local get-out-the-vote operation, and representing the neighborhood on the county party executive committee. Unfortunately, it is all too common for District Leaders to neglect these basic, grassroots party-building activities and instead focus on getting their favored candidates elected to local judgeships. If you would like to know more about what I have done since being elected leader, please check out my progress blog and sign up for the campaign mailing list.
