JOHN ROBERTS (HOST): What about the Supreme Court? [Donald Trump] comes out with 11 people that he says he'd put on the Supreme Court. I mean, this is 'Don't worry, conservatives, I'm with you here.' It really seems like he's got to go to great lengths to keep people with him. 

MICHAEL NEEDHAM: It was, and I think that was a great gesture. In some ways it's a microcosm of the Trump campaign. He puts out this list, it is a phenomenal list. Conservatives think fantastic. Donald Trump is saying, 'Where is Hillary's list? Let's talk about that.' And then later that night he said, 'But maybe I'll add to the list.' And so, kind of this great moment with Donald Trump and conservatives for some reason gets a question mark at the end, and I think what that causes is some people say this was really shrewd, this is how you make deals, this is how you negotiate. And other people say, well hold on, that's a little erratic, what's going on there, does he really mean it, is this a fraud? And so I think the challenge for Trump is to find those issues, give conservatives confidence, and then convince those people in the second who look at that question mark and see erratic behavior and say we're going to make them comfortable, we're going to make them come over and join the coalition.
