But many say this 10th debate made them nervous about the Democratic field.
Bernie Sanders was also pressed about his comments on "60 Minutes" about Fidel Castro, saying "Cuba is a dictatorship. I've said that 8 million times."
Seven Democratic candidates met on stage in South Carolina for the last debate before the state's primary and Super Tuesday.
The 10th debate of the presidential primary cycle was the last before the pivotal South Carolina primary Saturday.
Biden said winning South Carolina by even one percentage point would be "enough" for him to stay in the race.
What to watch for from the candidates in Tuesday night's debate.
"In none of them was he accused of doing anything, saying something nasty to a woman," Taylor said. "That is not who he is. Life has changed. I grew up in that world. It was a 'bro' culture."
Biden is still in second, with about 20% support, followed by Buttigieg, with 14.3%.
"I don't think you need a lot of advice from me on bravery," Buttigieg said, in part. "You seem pretty strong."
Coming off his win in the Nevada caucuses, Bernie Sanders talks about Michael Bloomberg, Donald Trump, democratic socialism, and what he would do if elected president.
One group of now mostly senior citizen organizers, known as The Reckoning Crew, is backing Joe Biden.
Candidates will have their first test with a Democratic electorate that is expected to be mostly minority — 60% of the turnout here on Saturday is expected to comprise black voters.
"Given how close the race is between second and third place, we ask that you take these steps before releasing any final data," Pete Buttigieg's campaign wrote.
However, 2020 candidate match-ups with Trump are close, CBS News poll finds.
Biden is ahead with black voters, but his support has receded since the fall, according to a new CBS News poll.
