I just disagree. News orgs write and broadcast info which they think is "newsworthy" (Read: their constituencies will have interest. Example: The Bloomberg News doesn't spend any time on sports. The Eugene Register-Guard, is spending pages on the upcoming game between the Univ. of Oregon and Ohio State)If you wait long enough, anything can happen. Who knows? It probably has already happened in some form. Maybe not the exact scenario you describe. That's probably why stories get dismissed by the national media every day while others get reported on.
If it doesn't fit the narrative they are looking for, it gets ignored. Very unscientific if you ask me.
But having said that, some news orgs with a slant will slant—or even spike—news stories. The most egregious of them all, right now, is Faux News, among the big ones. You couldn't get the truth out of them with a loaded pistol. Maybe water boarding, though. (I'm talking about outright lying to their viewers, not their political slant. Roger Ailes is a f'ing virus.)
