介绍： Hello, I'm Debbie Russ with the BBC news. The ex-Vice President of the United States, Joe Biden has sealed his comeback in the race to be the Democratic candidate for the White House. So far, Mr. Biden has beaten Senator Bernie Sanders in 9 of the 14 Super Tuesday primary state contests. Sophie Long reports from Los Angeles. The former vice president entered this race as the clear front-runner with it or to lose. Less than two weeks ago, it looked like he might do just that after a poor start to this primary season, but he is very much back in the running. So I'm here to report, we are very much alive. But Senator Bernie Sanders, the self-declared social Democrat from Vermont, still has the edge in western states, which due to their huge, delicate hall, could still carry him through. We are not only taking on the corporate establishment, we're taking on the political establishment.

大家好，我是黛比·罗斯，欢迎收听BBC新闻。美国前副总统乔·拜登在民主党总统候选人角逐中再次复出。到目前为止，在“超级星期二”初选中，拜登在14个州中的9个击败了参议员伯尼·桑德斯。请听苏菲·朗在洛杉矶的报道。这位前副总统现在在竞选中处于明显的领先地位，要么成功要么失败。不到两周之前，初选开局失利，人们认为他可能输掉竞选，但是他现在已经非常有希望了。我宣布，我们现在势头正足。但来自佛蒙特州、自称社会民主党人的参议员伯尼·桑德斯仍在西部各州占有优势，由于这些州的政治影响很大，桑德斯仍有可能获胜。我们不仅要与企业建制派较量，还要与政治建制派较量。
