CNN used to be way left of center back when Ted Turner was still running things, but it hasn't been for a couple of decades. In fact, except for MSNBC, the rest of the outlets on your list are just *barely* left of center, if at all.
You'd consider NPR "just *barely* left of center"? Wow!
Things are newsworthy if they are timely, have some significant public interest, are unusual or interesting, etc. Biden's son's laptop is none of those things
Absolute incontrovertible proof of the son of the current President smoking crack, patronizing Russian mob hookers, taking bribes from eastern European governments, etc. is a story of significant public interest, and there is no arguing this point while maintaining any credibility whatsoever. Notably, though, this is almost *verbatim* the excuse that NPR's managing editor used to explain why they refused - and still refuse - to cover the story.
