Which Candidates Got the Most Speaking Time in the Democratic Debate

Senators Elizabeth Warren of Massachusetts and Amy Klobuchar of Minnesota had the most speaking time of the six Democratic presidential candidates in the debate in Las Vegas, three days ahead of the Nevada caucuses on Saturday. This was the first debate in which two female candidates led the stage.

Former Mayor Michael Bloomberg of New York, making his first appearance in a presidential debate, came under fire from the other candidates for his past comments on women, stop-and-frisk policies and failure to release his tax returns. Mr. Bloomberg said he would release his tax returns soon.

The debate was far more heated than previous debates, with the candidates frequently interrupting each other and demanding time to respond to attacks.

The candidates also discussed their plans to deal with environmental issues. While all said they were resolved to fight climate change, they differed in their stances on whether fracking should be banned completely.

When Senator Bernie Sanders of Vermont was asked if he stood by his comments about whether billionaires should exist, he called it wrong and immoral for Mr. Bloomberg to own more wealth than the bottom 125 million Americans. Mr. Bloomberg, a multibillionaire, said he worked hard to earn his money and would be “giving it all away to make this country better.”

The debate ended with the question of whether the Democratic candidate with the most pledged delegates should be the party’s nominee, regardless of whether he or she has a majority required. Only Mr. Sanders agreed.
