I don't necessarily agree with you on how skewed the spectrum is.

Because as far as you can go on to the left, saying that Bernie Sanders is the only left leaning politician because no one's pushing for legitimately socialistic policies, you can do the same on the other side.

No one on the right is legitimately pushing for nationalizing major industries. Or literally criminalizing ethno-minority groups.

So the US is a two-party system and virtually every media outlet skews one way or the other, with few exceptions.

You have blatant skews to the right and blatant skews to the left.

And my point is that the vast majority of media that doesn't claim a blatant skew - does still skew left.
