BROOKE BALDWIN, CNN HOST: Another way to interpret these numbers here is you have 29 percent of Democrats polled support Biden and then the other 29 percent are split among the progressives, right?</s>GLORIA BORGER, CNN CHIEF POLITICAL ANALYST: Right.</s>BALDWIN: So between Sanders and Warren. So do you think that's just more evidence of how severely divided the party is right now?</s>BORGER: Yes, sure. The progressives are really divided. And Sanders and Warren are locked in a battle. They're looking at different parts of progressives. I think that Warren appeals to younger progressives, for example, better educated. Sanders more blue-collar, older. They're fighting for that wing in the party. That's another reason Biden continues to float above everybody else. Also, this notion of his electability. I've never heard as long, as I've cover politics -- I'm old enough to remember when Hillary Clinton used the electability argument, and that didn't work really well for her, and the inevitability argument, and that didn't work really well for. For Joe Biden right now, because Donald Trump is the Republican nominee, that electability argument worked very well with Democrats, more than half of whom think it's the most important thing a Democrat can be, which is a winner. They're looking for someone who can beat Donald Trump above all else.</s>BALDWIN: I want to ask you about that. We'll play the sound from Dr. Biden when she was talking to those teachers in New Hampshire.</s>BORGER: Oh, yes.</s>BALDWIN: So we'll let people watch it and be the judge and how affective it is. And then I'll ask you about it in a second. Gloria, stand by for me. Also ahead, the NRA has been rocked by these resignations. Two more board members have stepped down in the past couple hours, a former NASCAR driver and country music singer. We have details on that. And more Gloria Borger, coming up next.
