Glad to see this forum alive again.
I honestly believe that if a national network said "trump is terrible, trump is stupid" all day that they would still live. Their audience though would be 99% people who like hearing that. I wouldn't want want to call them "news" though. If you stay in the middle you will draw an audience from both sides and not just one.
A local station would fall much quicker for pulling mess like this because they already are limited to their DMA numbers for the most part.
