Bernie Sanders and Joe Biden were crowned the winners of the Democratic debate in Charleston by a poll taken of party-voting viewers.
The CBS News poll said he had made 'the best case to beat Donald Trump,' with 26 per cent naming him compared to to 21 per cent for Joe Biden.
The poll - and a similar online poll by The Drudge Report - suggested Sanders, who is now favorite to become the party's candidate, kept the momentum up as he was attacked on all fronts by the six other presidential hopefuls on Tuesday night in Charleston before voters cast their ballots in the South Carolina primary.
Several pundits said Sanders, although hit with hard questions about his record on gun control, why he praised authoritarian socialist regimes and how he would pay for his expensive policies, was able to maintain a lead.
Biden was also praised for bouncing back, as he put his stakes on winning the African-American vote in diverse South Carolina.
Bernie Sanders and Joe Biden have been hailed as the winners of the Democratic debate in Charleston, while Elizabeth Warren and the night's moderators were deemed the losers
Popularity contests: Bernie Sanders secured victory by three different measures, with Mike Bloomberg in second place each time
Both men came top of the most tweeted about list, with social media engagement now seen as a crucial way of measuring impact on voters.
And despite a previous fiery performance in Charleston from Elizabeth Warren, the Massachusetts senator didn't do enough to put her on top, although she went after Mike Bloomberg over his NDAs with employees, accusing him of telling a staffer to 'kill it' when she told the former New York City mayor she was pregnant.
Also earning the loser status were the CBS moderators, including Norah O'Donnell and Gayle King, who struggled to rein in the candidates from shouting over one another and ignoring time limits. O'Donnell even tried to end the debate prematurely, forgetting they would come back after a commercial break.
BERNIE SANDERS: TOOK A BASH BUT WASN'T ENOUGH TO TAKE HIM OUT (WINNER)
Sanders took lots of the blows but also held his own when he got into shouting matches. When asked by a CBS moderator how he planned play for his plans, he responded coolly, 'How many hours do you have?'
CNN's political analyst Chris Cillizza said that if nothing changed during the debate, Sanders will 'emerge on March 4 with a very clear delegate lead', adding that 'nothing fundamental changed tonight'.
Politico's David Siders added: 'Sanders may have had the best night, functionally, since nobody hit him in a way that is likely to damage him.
'If Sanders had been bruised or Biden faltered, the trajectory of the race might have changed. Instead, Sanders and Biden head into the South Carolina primary largely where they were before, with the rest of the field falling in behind them.'
Vox said it would state the obvious and declare Sanders as the frontrunner, pointing out Sanders' double-digit lead in national polling.
Reporter Dylan Matthews added: 'So to win on Tuesday night, Sanders just needed to hold his own. And he did. Despite candidates lobbing both familiar (abolishing private insurance, past anti-gun control votes) and new (praising left-leaning dictators' social programs) attacks on him, Sanders didn't lose his cool, and his opponents were never able to really dig into him.'
JOE BIDEN: BOUNCED BACK (WINNER)
Joe Biden, who said he intends to win in South Carolina, blasted Sanders for voting against the Brady bill gun control measure, and referenced the Charleston church shootings
Although Biden only placed fourth in Drudge's report, earning 11.4 percent of the votes, many pundits are also hailing him as a winner.
Biden has called South Carolina his 'firewall,' even before his dismal finishes in Iowa and New Hampshire - putting all his hope on the diverse state.
And on Tuesday, Biden emphasized his affinity for issues dear to black voters and reminded them of his decades-long advocacy.
Overall, Biden's performance was steady when he most needed it and he expressed some confidence.
The Washington Post noted that Biden is currently 'the leading candidate in South Carolina' but did touch on his complaining about not getting enough time during the debate.
'Best debate performance yet from @JoeBiden — he's best when his back is against the wall,' wrote Jennifer Palmieri, former spokeswoman for Hillary Clinton and Barack Obama.
MIKE BLOOMBERG: COULDN'T BOUNCE BACK (LOSER)
The good news for Bloomberg is this debate didn't go as badly as Las Vegas. The bad news is no one is grading on the curve.
He ceded prime target status to Sanders, but took his share of criticism. He still got scratched and occasionally came off as brittle.
Warren continued to be his nemesis, slamming him for funding Republican senators and for accusations that women at his company were mistreated. She brought up an allegation that Bloomberg had told a pregnant woman in his employ to 'kill it' - which Bloomberg heatedly denied.
Later, he tried to make a joke about how everyone else onstage should have been scared to show up 'after I did such a good job of beating them last week,' which fell flat.
CNN pundit Chris Cilizza offered a different version, suggesting it was Pete Buttigieg who was the best performer
Warren had to make a difficult straddle at the debate - she wanted to spotlight her liberal positions to pry voters from front-runner Sanders, but she also had to make a pitch for why they should back her rather than him
ELIZABETH WARREN: SENATOR TARGETED SANDERS AND BLOOMBERG (LOSER)
Warren had to make a difficult straddle at the debate - she wanted to spotlight her liberal positions to pry voters from Sanders, but she also had to make a pitch for why they should back her rather than him.
She has been hesitant to fully voice her criticism of Sanders but leaned into it Tuesday night. 'Bernie's winning right now because the Democratic Party is a progressive party and progressive ideas are popular ideas,' she said.
Vox wrote: 'With the exception of a few minutes at the start of the debate, Warren failed to draw a distinction from Sanders.
'She attempted to make the point that she was just like Bernie, only better, because she could actually make her policies become reality. But she didn’t hammer home this argument or make it strenuously enough that it created a lasting effect.'
Warren also reprised her attacks on Bloomberg, which might not help her win votes, but clearly helps her raise money.
The debate featured chaotic exchanges where multiple candidates sought to talk over each other, with CBS moderators Norah O'Donnell and Gayle King losing all control of the discussion
THE MODERATORS: COULDN'T CONTROL THE CANDIDATES (LOSER)
The debate featured chaotic exchanges where multiple candidates sought to talk over each other, with CBS moderators Norah O'Donnell and Gayle King losing all control of the discussion about 40 minutes into the debate, either failing to referee or being completely ignored by the over-eager candidates.
CNN's Van Jones tweeted: 'Wayyyy too much time was wasted at tonight's #DemDebates on a bunch of guys yelling at each other over and over and over and over again. Do you agree?
Once the candidates wrapped up, O'Donnell tried to shut down the debate prematurely, but King had to quickly correct her, saying it wasn't quite over yet.
Vox compared the CBS team to substitute teachers, quipping: 'Did you ever have a substitute teacher who was so mild-mannered, and commanded so little natural respect and authority, that you and the rest of your middle school class quickly realized you could just shout him out until he agreed to just crawl behind his desk and read a book while you did whatever you wanted for 45 minutes?
'That’s basically what Tuesday night’s debate felt like, except for two full hours.'
