Anybody framing cancellations of shows losing copious amounts of money as political is just gaslighting to turn a loss into a political attack.
The reason people initially believed the tweet saying The View was getting canceled is because, after the Late Show cancellation, it's actually very likely. The View's ratings are only slightly better than the Late Show, and why'll I admit I don't have the entire show budget, just the hosts are extremely expensive. From what I've seen, these are the most recent annual salaries:
Whoopi Goldberg- $8 million
Joy Behar- $7 million
Sunny Hostin- $2 million
Alyssa Farrah Griffin- $2 million
Sara Haines- $1.5 million
Ana Navarro- $250,000
The hosts combined made almost over $6 million dollars a year more than Colbert made, while only having about 200,000 more viewers. It looks like Rosie O'Donnell sees the writing on the wall and is preemptively setting it up as an attack against Trump when financials would be the real reason if it did happen.
But The View has an easy way to save money. Dump its two most expensive hosts and bring in less expensive talent. Would it be enough? No idea without the additional costs behind the show and how much revenue it brings in, which can't be significantly more than the Late Show.
