CHARLIE ROSE (CO-HOST): So how does [Donald] Trump handle the fact that he's not going to be able to get the endorsement of some people that generally a Republican nominee would have?
MARK LEIBOVICH: I think you do it in pure Trump fashion. You're dismissive of it. You ignore it. And you say, look, I'm running a different kind of campaign. I'm a different kind of candidate. I wouldn't expect these traditional political figures to get behind me. Having said that, look, this is -- the general election is a time to consolidate your support within the party. And this is not going to be helpful in that regard.
GAYLE KING (CO-HOST) Donald Trump says that he will pivot, that he will change his tone as we head to the general election, but your article seems to indicate that you do not seem convinced, Mark, of that.
LEIBOVICH: Well first of all, he's talked about pivoting maybe like eight or nine times in the last two months. It generally holds less than 48 hours, if that. So his recent history is not very good. It's holding a pivot. But look, I mean, there is this sort of, not a blank slate, but certainly a rethinking that goes on generally in this season once you have two presumptive nominees. The question is, has Trump just done too much damage and has he defined himself so deeply that it's really a no turning back situation for him?
