[Lu Stout:] Coming to you live from Hong Kong, you are back watching News Stream. Now, Hillary Clinton's campaign calls it, quote, a new low in the contest for the U.S. Democratic presidential nomination. The Democratic frontrunner's team is responded to remarks made by rival, Bernie Sanders. He said on Wednesday, that Clinton is not, quote, "qualified to be president, accusing her of taking tens of millions of dollars from special interest groups through a group that supports her." Now the attack follows Sanders' win in the Wisconsin primary, though he still faces a steep climb. Now, Clinton only needs to win 36 percent of the remaining delegates to get there. Now, Sanders has to capture more than double that. Now, let's bring in our senior political correspondent Brianna Keilar for more on this. And Brianna, tell us more about this bitter battle that is brewing between Sanders and Clinton.
[Brianna Keilar, Cnn Correspondent:] Hi, Kristie. Bernie Sanders said what he said about Hillary Clinton, that she isn't qualified to be president at a rally before about 10,000 people in Philadelphia. I'll tell you, I was at this rally, this was like red meat to his supporters. They were eating it up. Bernie Sanders clearly not responding kindly to the Clinton campaign's new strategy to go after him more aggressively.
[Sen. Bernie Sanders, 2016 Democratic Presidential Candidate:] I don't believe that she is qualified.
[Keilar:] Bernie Sanders lashing out at Hillary Clinton.
[Sanders:] I don't think that you are qualified if you get $15 million from Wall Street through your super PAC. I don't think you are qualified if you have voted for the disastrous war in Iraq.
[Keilar:] The war of words between the two presidential Democratic candidates escalating. Sanders claiming...
[Sanders:] She has been saying lately she thinks that I am, quote, unquote, "not qualified to be president."
[Keilar:] But Clinton's campaign denies she ever said he wasn't qualified.
[Clinton:] The presidents who are successful know what they want too, and they know how to do it.
[Keilar:] Clinton is pointing to an interview Sanders did with the "New York Daily News," where he struggled to identify how his administration would break up the big banks, elaborating in an interview with Chris Cuomo.
[Clinton:] I was, I think, a little, you know, surprised that there didn't seem to be a lot of substance to what he was saying.
[Keilar:] Clinton now taking this line of attack on the campaign trail, that Sanders is unprepared to be president, and even questioning whether he's a Democrat.
[Clinton:] He himself has said that he never was. He never ran as a Democrat until he started running for president.
[Keilar:] Now, the spokesman for the Clinton campaign tweeted shortly after Bernie Sanders said what he did, Kristie, "Bernie Sanders, take back your words about Hillary Clinton." And it's interesting to note both of these campaigns at this point are fundraising off of this back and forth. It's also important to note, this is the most contentious that we have seen the Democratic side of the presidential race, that real testiness is something that has been reserved pretty much for the Republicans.
[Lu Stout:] Yeah, the gloves are off certainly in the Democratic race now. And meanwhile, the battle for New York, Brianna. We know it's a home state for both the candidates. Who at this point has the upper hand there?
[Keilar:] Right now the polls show Hillary Clinton with the lead. And it is her home state, but it's also where Bernie Sanders was born. This is Hillary Clinton's adopted home state. This is where she became a senator after Bill Clinton left the White House and she was no longer first lady. There are so many pledged delegates at stake: 247. So, this is a giant piece of the pie. For Bernie Sanders, it is so important that he win New York if he is going to have a path to the White House. And for Hillary Clinton, is it a absolute must? No, but it would be terribly embarrassing if she were to lose her adopted home state.
[Lu Stout:] All right, Brianna Keilar reporting live for us. Thank you, Brianna. Now, on the Republican side, Donald Trump is the heavy favorite in New York. He hit on some familiar themes during a campaign speech on Wednesday night.
[Trump:] We are going to have a strong border. We are going to build the wall. It will be a real wall. A real wall. Who is going to pay for the wall? Who? By the way, 100 percent.
[Lu Stout:] And the latest count shows Donald Trump would need to win 60 percent of the remaining delegates in order to get to the magic number, 1,237 and clinch the nomination. Ted Cruz would need to win 88 percent, John Kasich would need to win an unwinnable 125 percent. Now, business is booming at a small factory in central Mexico thanks to Donald Trump. It's turning out masks of the billionaire. Rafael Romo went to check it out.
[Rafael Romo, Cnn Correspondent:] It's a factory bustling with activity with workers pouring liquid plaster onto molds, painting, refining and creating all kinds of different designs.
[Unidentified Male:] It's a very manual process.
[Romo:] This mask factory in central Mexico has been busier than ever in the last few months. And it's all thanks to the unexpected popularity of not a Mexican, but an American presidential candidate. Take a look at the strands of artificial hair neatly placed and quaffed by this worker.
[Unidentified Male:] We weren't making this mask with actual hair, and some of our customers asked for it, and it has to be the hair. so, this is the deluxe version.
[Romo:] You've probably already guessed. It's Donald Trump's mask and this factory executive believes demand will only grow in the next few months.
[Unidentified Male:] We think maybe because of the polls that he will be the candidate.
[Romo:] The last shipment of the Donald Trump mask came out of this factory two weeks ago. It was 10,000 masks, 80 percent of them were sold in the United States and the rest here in Mexico. There's only one mask beating Donald Trump's in sales, that of Joaquin "El Chapo" Guzman, the drug lord captured in January after a spectacular tunnel escape from prison last summer. The mask that comes with the prison outfit has been flying off the shelves.
[Unidentified Male:] Yeah, totally sold out. We sold El Chapo masks in customs in all Mexican territory in all America U.S. territory and we sold in Australia, for example.
[Romo:] Wait, wait, wai, El Chapo masks being sold in Australia? There is still a chance for Trump to compete with El Chapo, but only if he can win the Republican Party's presidential nomination. The great irony, making a fortune off of two highly controversial men whose only thing in common is dominating the headlines. Rafael Romo, CNN, Hutapec, Mexico.
