I'm not so sure that CNN, ABC, or CBS qualify as "legitimate" news sources anymore, given that they have all folded to Trump like a cheap tent. On MSNBC even Scarborough traveled to Mar-a-Lago and made a preemptive surrender right after the election last year. The WSJ is a right-wing Murdoch property and has been for years, and the WaPo has moved sharply to the right (and shed many of its top reporters) since Bezos made buddy-buddy with Trump last year. And the NY Times has become a relentless bosiding joke, imo. So it is quite possible for him to see little but news that either praises him or at least rarely criticizes him in any substantial way. His press conferences are a true joke, with many right-wing reporters asking him softball, promotional questions that allow him to brag on himself.
I do agree that he's a classic narcissist, and I do think that it's eaten away at him for years that that the people he claims to despise - the dreaded liberal elites - are the very people whose support and respect he's wanted for decades, but can never get because of his loutish and crude behavior and the fact that he's just a shitty human being. And it's also true that he holds most of his MAGA base in contempt and wouldn't be caught dead actually living in or staying for very long in the places where most of his supporters reside. But I do think our "legitimate" news media is rapidly being bought out by right-wingers like Bezos and Musk and is being pushed to the right.
