The 504 Democrats are a NYC-wide Democratic club focused on disabled rights. I came across a partial list of their 2009 endorsements (the full list is not up on their site at this point). These endorsements are for three city council candidates I have been supporting for some time now. The 504 Democrats have endorsed:

Council District 25 (Queens): Daniel Dromm (Daniel Dromm has also received the endorsements of Stonewall Democrats, the United Federation of Teachers, and ChangeNYC, among others)

Council District 3 (Manhattan): Yetta Kurland (Yetta Kurland has also gotten the endorsements of Downtown Independent Democrats, ChangeNYC, and the New York Blade, among others)

Council District 33: (Brooklyn): Jo Anne Simon (Jo Anne Simon has also gotten the endorsements of the Central Brooklyn Independent Democrats, ChangeNYC, and Lambda Independent Democrats, among others)

I find it interesting that, at least on these three races, Change NYC, 504 Democrats, and I all agree.

Here is the mission statement of 504 Demorats:

The 504 Democratic Club is a New York City-based coalition of Democrats working towards inclusion of people with disabilities in the political and social fabric of society. Club members hail from all five boroughs, reaching across every conceivable line to include a richly diverse group of people with disabilities, public officials, friends and family who support the concepts set forth in Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990.
