As far as I can see, everyone is bashing NewsNation. Even with the scandals and chaos going around the station, there should be definitely a room for NewsNation for many reasons. First of all, they are quickly finding an audience thru new media outlets and MVPD services, and they are slowly picking up new deals with both traditional and MVPD providers. Second, there is space for a right-leaning news outlet to compensate for the direction Fox News and Newsmax have taken. Maybe you've got executives which have some kind of relationship with a former President, but, as far as I can see, there is not Fox-like rhetoric, and, if they finally make the programming and content right, NewsNation can easily target the more traditional conservative audiences by making their news-based pundit programming as a selling point to disaffected viewers. Finally, they have a larger network of resources (the Nexstar local stations, WGN Radio, The Hill, BestReviews) that they can boost the network's audiences, and make additional programming with an infotainment focus. Live PD could also be a fit for their weekend primetime hours, as one of you suggested, as their direction into true crime-based specials with the Missing in America franchise (which should be spun-off as a weekly show) can also attract viewers. They also need to use more their wasted staff, like Rich McHugh, which could do a semi-regular, long-form investigative series.
The thing is using the Nexstar stations as their only external source is not going to be easy enough to attract an audience, they should use the rest of their national brands and resources to make additional programming. The other problem is that their transitional Blue Bloods/news/opinion schedule is making both audiences and advertisers to go away from the network. They should go all-news/opinion/infotainment as fast as they need to build an audience.
