[23] One of the most memorable moments from the debate, which drew an average of 15.3 million viewers, a record for a Democratic debate,[24] came when Sanders replied to a question about Clinton's email controversy that the American people were "sick and tired of hearing about your damn emails", which drew cheers and applause from the audience and a smile and handshake between the two candidates.
Fact-checking by the Associated Press and USA Today pointed out mistakes in both of their presentations: specifically, Clinton was considered inconsistent in many of her policy stances, particularly with regard to the Obama administration's handling of the Syrian Civil War as well as the Trans-Pacific Partnership agreement that Clinton supported as Secretary of State, but changed to opposing while a candidate.

During a break, highlights of the debate were shown by Hari Sreenivasan with political commentary from Lisa Desjardins, Amy Walter, and Tamara Keith weighing in on what had been said.
The candidates debated on race relations, the size of government, funding their goals, Medicaid/Medicare, campaign contributor's influence, the prospect of a first woman president, affordable college, reducing areas of government, readiness for an attack on America, Henry Kissinger, Russian relations, the U.S. role with respect to refugees, influential leaders on foreign policy, and criticism of President Barack Obama.

[110] In response, the organization released a press statement on its Facebook page stating that "[i]n consultation with our chapters, our communities, allies, and supporters, we remain unequivocal that a Presidential Town Hall with support from the DNC does not sufficiently respond to the concerns raised by our members", continuing to demand a full additional debate.
[108] Harvard professor Lawrence Lessig, who announced his campaign on September 6, criticized the requirement that Democratic candidates must earn at least 1% in three major national polls in the six weeks before the debate.
His criticism was centered on the fact that he was excluded from most polls because the Democratic National Committee (DNC) did not officially welcome him to the campaign as it had done for all five other candidates.
