JAKE TAPPER, CNN: I want to ask you about Howard Schultz, the former Starbucks CEO, who says this weekend he's seriously exploring a self-funded independent bid for president. He told "60 Minutes" that he thinks both parties are engaged in what he called revenge politics and not acting in the interest of the American people.
Do you have any concerns that a very wealthy independent with a message like Schultz's could play spoiler in 2020?
REP. JULIAN CASTRO (D-TX): Well, you know, first, I would say that I have tremendous respect for Howard Schultz.
When I was HUD secretary, I had an opportunity to visit with him. I know that, you know, he's done some impressive things in business. Obviously, if he runs, it's going to make an impression on the race.
But I do share that concern. I have a concern that, if he did run, that, essentially, it would provide Donald Trump with his best hope of getting reelected.
Just the other day, there was a fairly comprehensive poll taken that showed, essentially, right now, that the president has a ceiling of about 41 percent or 42 percent in terms of support for him, no matter which Democratic candidate they polled against him.
So his only hope, if things stayed the same -- and that's a big if -- is essentially to get somebody else, a third party, to siphon off those votes. And I don't think that that would be in the best interest of our country. We need new leadership.
And so, you know, I would suggest to Mr. Schultz to truly think about the negative impact that that might make.
The only other thing I will say about that is that we can't both-sides this to death. It's not -- yes, I agree that there are things that Republicans and Democrats do need to improve upon, but there's a real difference between any of the folks who have said that they want to run on the Democratic side and Donald Trump.
I mean, that's become so clear. So, it's not all the same thing.
