Right wing media doesn't 'both sides' anything to avoid being partisan.I think it's easy to point the finger at politicians. And perhaps that is where the blame lies.
But I also believe strongly that it's much deeper than that - our society is an absolute mess, and our elected officials feel like they can't risk (generally) speaking the truth about all this nonsense and risk alienating someone who might vote for him or her.
We live in a world where the media feels compelled to "both sides" issues lest they look partisan. When the reality is one side is so far gone it's not even a "political" debate any more.
There is no way to fix this because of the alternate reality right wing media has created over the past 35 years
The only times they 'both sides' something is to take the heat off their preferred narrative. There's a lot of talk about when Rand Pauls neighbor beat the crap out of him going round.
With Fox, Spectrum, and now likely twitter, there's less and less effort being put in to even trying to feign partisan coverage.
