From the April 19 edition of Fox News' The Kelly File:
MEGYN KELLY (HOST): We heard from Senator Ted Cruz earlier tonight, and we also just heard from Donald Trump, and the messages from each candidate sounded very different than we've heard from them in the past. If you missed Senator Cruz, here's a bit of him now.
Unity, and speaking about how America is at a point of choosing. And you heard Donald Trump tonight sounding, you tell me, more presidential? Senator Cruz, not “Lyin' Ted,” did you notice that? Back with us now, Ben Domenech, publisher of The Federalist, and Monica Crowley. Fox News contributor and host of The Monica Crowley Show on radio. Monica, what do you think? I don't know if I've ever heard Donald Trump call Ted Cruz “Senator Cruz.”
MONICA CROWLEY: Yeah, there was definitely a change in his tone, and in his rhetoric tonight. I mean, this is classic Donald Trump, in the sense that he's really in his element when he's the victor, as he was tonight. He also hit all of the themes that got him to this point, Megyn. He hit illegal immigration, the economy, jobs, repealing Obamacare, strengthening the military. These are the things that got him to be the Republican front-runner.
CROWLEY: Discipline. Right. And now he realizes that this campaign is in a new phase, and there is a natural maturation of both the candidate, and his campaign that's going on here, with this hiring a very seasoned, experienced political operatives that know the process, delegate hunters like Paul Manafort, who know how to wrangle delegates and protect them once they''re in their camp.
So he understands now that, you know, this campaign just got really real. And if he wants to win, he has got to go along with, I think a much more substantive and responsible tone, because now he understands -- he is not just speaking for himself --
KELLY: Yeah, he's already giving fewer interviews, we've seen fewer tweets from him, he seems to be just more disciplined.
