Yes, Boomer’s statement that ‘no one has ever won the presidency without some media network support’ is just plain wrong.
You gave the best example with Reagan.
And I can’t think of any network who suppprted Nixon and both Bushes.
Well, yes, but the reporters actually got along well with Reagan, who most of them liked personally, and they could have been harder on him than they were. And this was 1980, when the media still had some semblance of restraint.
