It's quite a stretch to compare impressions of Newsnation and Real America's Voice (which is cringeworthy just to type). Newsnation is a facts-based news effort making an appeal to ALL potential viewers from an unbiased position (that we now know has shifted center-right). RAV is explicitly targeting hard-right viewers with explicitly biased programming, essentially giving viewers what they want to hear. Yes, them having more impressions is indisputable. But one is offering apples and casting a wide net, the other is offering oranges and shooting fish in a barrel. "Why doesn't anybody like my artisan cookie while Miller Lite is selling so well?"
Also, Live PD is not "the only thing possible that could ever save NewsNation". We get that the show is missed, and yes, it's viewership numbers were indisputable. But unless they make it the Live PD channel, one or two hot hours out of a week's worth of programming does not make a smash hit network. Also- production costs? Which carries more liability- Dan Abrams behind a desk in a dark room or a full camera crew riding around with on duty cops? Does anyone think Nexstar wants to spend that money or bear that responsibility?
