Transcript for Trump says he is ahead in the polls ahead of the first Democratic debate
political analyst Matthew dowd who is joining us from Texas. Matthew. I'm going to spare you a question on ufos and get back to more terrestrial matters around presidential politics. This president, Donald Trump, seems fixated a bit on Joe Biden but how worried do you really think he should be? Yes, Biden may be polling well but it is so early in this process. Well, a couple things, Dan, really, first, I don't ever sense the president worries about too much because as we've seen and we've seen in these interviews he seems to have a great capacity to deny reality, even reality of his own campaign polling which he denied existed but there may be a question about whether he was ever shown those himself. The other thing about this is, we have to keep in mind these as we saw in 2016, polls and the race can change suddenly. I think the president would be behooved to admit reality and to say he's behind and hasn't been reaching out enough, but Democrats would also be -- it's important for Democrats to understand polls can change suddenly. Polls can change and they don't often indicate where the American public is, so each side actually has to look at this race realistically. Volatility is the one constant seemingly. The other news this morning, these democratic debates, Rachel was just talking about them. They've been divided into two nights because there's so many candidates. Night two is when you're going to see most of the heavy hitters including Joe Biden. And I'm wondering does Biden run the risk of being up there on stage with a bunch of younger contenders like Pete buttigieg and kamala Harris. Is that risky for him? You know, this reminds me watching this unfold and having two nights of debates with multiple candidates reminds of the women's world cup and the stage level and who is going to emerge from that stage to go to the next level in this. I think Joe Biden, I think he does have some worries about this because any time you put him on stage next to somebody else people may or may not know can raise their stature in relation to Joe Biden. But there's pressure on everybody in this. There's pressure on Joe Biden to prove that, yes, he does still have the gravitas and, yes, he's ready to be president but also puts pressure on the sort of more unknown candidates to get themselves known as we start into this process. The other person I'll mention on the first night I think has a real opportunity because she's not on the same stage as Joe Biden and Bernie Sanders is Elizabeth Warren. She's been rising in the polls more than anybody else and she's sitting on a stage without some dominant other characters involved in that so both nights I think are going to be fascinating to see who emerges from this stage area of the presidential race. Of course, you'll have lots of lesser known candidates scrambling for their moment in the spotlight as well. Matthew dowd, we really appreciate your analysis. On Saturday mornings here, thank you. A reminder, you can see George's full interview with president trump in a prime time special this Sunday at 8:00, 7:00 central right here on ABC.
