Fox News has been going more left wing lately. With CNN and MSNBC going full orange man bad, Fox News saw an opportunity to change their image and be what CNN was widely considered before: the go to network for both sides for hard hitting news. It actually makes sense from a business perspective. Conservative viewers are going to watch pretty much no matter what, but liberals aren't. If Fox can lure more liberals with a little pandering, they can pull people away from CNN and MSNBC and make them irrelevant.
