ABC Democratic Debate Highlights 2015: The Best Video Clips, Moments, Questions, Insults And Gaffes From Democrat Candidates [VIDEO]

Saturday night's Democratic presidential debate came across as the most fiery one yet, as the three candidates sparred in part over gun control and past foreign policy decisions. But there were also moments of unity, and perhaps none will get more attention than Vermont Sen. Bernie Sanders' apology to former Secretary of State Hillary Clinton for one of his now-former campaign's staffers unethically accessing the front-runner's voter information. All candidates said they agreed the party needed to move beyond the controversy to address issues that Americans care about.

Going into the debate, Clinton continued to lead the field, polling at 59 percent, according to a recent Monmouth University survey. Sanders, her closest competitor, polled at 26 percent, and former Maryland Gov. Martin O’Malley polled at just 4 percent. In searching for videos available immediately after the debate, those featuring O'Malley proved elusive. Here are some of what we could find:

Sanders doesn't blink before answering whether Wall Street's going to like a Sanders presidency. The answer is not a shocker, given Sanders' sharp and repeated criticisms of Wall Street and wealth disparity:

Clinton ended the debate with a "Star Wars" line, quoting a familiar expression from the movies:

Sanders called for criminal justice reform and an end to institutional racism:

A bit awkwardly, ABC opened to an empty podium after a commercial break:

Clinton controversially said we're now "where we need to be" in the fight against ISIS. Many Republicans, including presidential candidate Jeb Bush, took to Twitter to counter her assertion.

No @HillaryClinton - We are not "where we need to be" in fight against ISIS. #DemDebate https://t.co/PFPpF5lADy

The debate, hosted by ABC, was the third of six planned for the Democrats. The debates are considered important times for struggling candidates to gain support, and some Sanders and O’Malley supporters have complained that the low number of debates unfairly works to favor Clinton.
