The NJDC served as a liberal watchdog on the lawful activities of the religious portion of the Right, acting to raise public awareness about efforts to undermine the wall between church and state.

[2] The group was replaced on a de facto basis in 2017 by the Jewish Democratic Council of America, which began its activities three months ahead of schedule because of President Donald Trump's perceived equivocal response to the 2017 Charlottesville march and violence.

Its stated priorities included:[9] In October 2008, the NJDC held a conference in Washington, D. C., at which then vice presidential candidate Joe Biden was the keynote speaker.

It was noted that "In 2008, the NJDC trained nearly 100 surrogates to speak around country, according to [executive director Ira] Forman, ran newspaper ad campaigns in pivotal swing states, sent 350,000 targeted pieces of mail to Jewish households, dropped 35,000 pieces of literature in key Jewish neighborhoods, and ran Internet and Google word search campaigns".

[14] The NJDC approved of the Obama administration's policies such as the 2009 stimulus package,[15] and the president's decision to pull out of Durban II,[16] the UN conference against racism which has been known to be a forum for anti-Israel agitation.
