PBS高端访谈:奥巴马呼吁要从实际出发（在线收听）

AMNA NAWAZ: We turn now to the Democratic presidential race. Over the weekend, candidates still trying to break through in the crowded field headed West.

SEN. AMY KLOBUCHAR (D-MN), Presidential Candidate: Hello, Nevada Democrats!

AMNA NAWAZ: As impeachment news consumes Washington, a show of force by the 2020 Democratic candidates in Nevada.

SEN. KAMALA HARRIS (D-CA), Presidential Candidate: This is a fight to end that national nightmare called Donald Trump.

AMNA NAWAZ: In Las Vegas Sunday night, 14 of the 2020 candidates made their pitch to Nevadans, who'll vote third in the party's nominating contest.

DEVAL PATRICK (D), Presidential Candidate: I'm confident there is a path.

AMNA NAWAZ: The lineup included former Massachusetts Governor Deval Patrick, who entered the crowded race just last week.

HARRY REID (D), Former U.S. Senator: When we get that nominate, we're all going to join together.

AMNA NAWAZ: Former U.S. Senate Leader Harry Reid, still a giant in the state's politics, made an appearance and a call for unity. But beneath the surface, the struggle continued over what kind of Democratic nominee should lead the party next, a centrist like former Vice President Joe Biden.

JOSEPH BIDEN (D), Presidential Candidate: The risk of nominating someone who wouldn't beat Trump is a nation and a world that our children and our grandkids won't want to, won't want to live in.

AMNA NAWAZ: Or a progressive like Massachusetts Senator Elizabeth Warren, who often warns against running what she calls a safe campaign.

SEN. ELIZABETH WARREN (D-MA), Presidential Candidate: We're not going to change it by a nibble here and a little bit of change over there. We're going to change it with big structural change.

AMNA NAWAZ: It came a day after former President Barack Obama, a moderate Democrat, made rare comments on the 2020 race and a veiled criticism of that big structural change. Mr. Obama said This is still a country that is less revolutionary than it is interested in improvement. They like seeing things improved, but the average American doesn't think you have to completely tear down the system and remake it. He warned candidates to pay some attention to where voters actually are and that we also have to be rooted in reality.

MICHAEL BLOOMBERG (I), Former Mayor of New York: I got something important really wrong.

AMNA NAWAZ: Meanwhile, another potential late addition to the Democratic race, Michael Bloomberg, apologized for the stop-and-frisk policing policy he led while mayor of New York, and has since defended as a means to combat crime.

MICHAEL BLOOMBERG: I spoke with many of the innocent people affected, and listened to their frustrations and their anger.

AMNA NAWAZ: The policy, granting police broad authority to detain and question people, overwhelmingly impacted people of color, and is largely seen as out of line with the current Democratic Party.

MICHAEL BLOOMBERG: I was wrong, and I am sorry.

AMNA NAWAZ: Today, Bloomberg picked up a key endorsement from Stephen Benjamin, mayor of Columbia, South Carolina, and one of the state's highest-profile black politicians, who applauded Bloomberg's apology.

阿姆纳·纳瓦兹：我们现在将目光聚焦到民主党总统竞选上。周末，候选人们试着挤过朝向西部的拥挤田野。

参议员艾米·克罗勃査，总统候选人：内华达州的民主党人，你们好！

阿姆纳·纳瓦兹：弹劾的消息在华盛顿引起了轩然大波，2020年大选的各民主党候选人在内华达州各显神通。

参议员卡玛拉·哈里斯，总统候选人：这是一场战役，目的是结束美国的噩梦，这个噩梦叫做唐纳德·特朗普。

阿姆纳·纳瓦兹：周日晚上，在拉斯维加斯，14名2020年的民主党候选人向内华达州选民铆足了劲儿，内华达州是民主党提名竞选中第3个投票的州。

德瓦尔·帕特里克，总统候选人：我相信是有一条路的。

阿姆纳·纳瓦兹：参加的候选人有前马萨诸塞州州长德瓦尔·帕特里克，他是上周加入庞大竞选阵容的。

哈里·里德，美国前参议员：我们得到提名后，就会团结在一起。

阿姆纳·纳瓦兹：美国前参议员领袖哈里·里德，他依然是内华达州政坛的风云人物，他现身到场，呼吁民主党团结起来。但在平静的表面下，抗争依然在持续，焦点在于下一步应该由哪位民主党提名者引领民主党，其中一位中立派就是前副总统乔·拜登。

乔·拜登，总统候选人：提名者无法击败特朗普的风险是美国人民乃至全世界儿童和子孙后辈都不想看到的，大家都无法忍受在这种情况下生活。

阿姆纳·纳瓦兹：还有改革派，比如马萨诸塞州参议员伊丽莎白·沃伦。此人经常警示大家不要做保守的竞选。

参议员伊丽莎白·沃伦，总统候选人：我们想要的改变不是一点点而已。我们会进行重大的结构性改革。

阿姆纳·纳瓦兹：在伊丽莎白作此言论的一天前，前总统巴拉克·奥巴马——持稳健态度的民主党议员，一反常态地对2020年的竞选做了评论，他还公开批评伊丽莎白所提出的结构性改革。奥巴马说，相较于革命性，美国其实对提升自己更感兴趣。美国人希望看到情况有所好转，但一般的美国人会觉得不必彻底改变并重新建立另一个体系。特朗普警示候选人关注选民的立场，植根于现实。

迈克尔·布隆伯格，前纽约市市长：我之前对一件重要事情的看法是错误的。

阿姆纳·纳瓦兹：与此同时，还有一名最近才加入民主党竞选阵容的人，他就是迈克尔·布隆伯格。他为自己担任纽约市长期间所倡导的盘查监管政策表示道歉，从那以后，他就一直在捍卫与犯罪做抗争的方式。

迈克尔·布隆伯格：我跟很多受到波及的受害者进行了交谈，我听取了他们感到失望挫败的地方和他们的愤怒。

阿姆纳·纳瓦兹：这个政策允许警方有很大的权限，可以拘禁并质问一些人，这极大地影响了有色人种，很多人认为这样的做法不符合民主党的风格。

迈克尔·布隆伯格：我之前做错了，对不起大家。

阿姆纳·纳瓦兹：今天，迈克尔·布隆伯格获得了斯蒂芬·本杰明的支持，后者是南卡州哥伦比亚市长，也是该州高调的黑人政客之一。他为斯蒂芬·本杰明的道歉而鼓掌。
