People who have spent more time quantifying this
disagree. CNN’s primetime programming leaned further left than MSNBC’s starting around 2015. Also, when Jeff Zucker took over CNN in 2012 he stated that his goal for the channel was to offer an
"attitude and a take" to viewers, which he did, until he left the channel in 2022.
But boy, it sure sounds commanding when you declare something to be “objectively incorrect”, then don’t provide any objective evidence at all to back up that viewpoint!
Did you even read the article you posted? Or did you just google for something that you thought would support your argument? Because I don't think that article says what you think it says.
"First, the measure appears to have face validity: the raw densities of the weighted CF score per channel, displaying remarkable similarity between CNN and MSNBC (weighted CF score of –9.7 and –14.1, respectively), and a much more right-leaning Fox News (weighted CF score of 49.8)."
Note that the weighted CF score of CNN over the surveyed period is closer to centre than that of MSNBC.
"Programs on Fox News are on average more conservative than programs on CNN and MSNBC. Our program-level measures reveal, at least based on the guests that appear on the show, popular primetime news shows on CNN—such as
Anderson Cooper 360 or
CNN Tonight—are more left leaning than well-known evening shows on MSNBC such as
The Rachel Maddow Show or
The 11th Hour with Brian Williams." This does point to some specific programs being more left than some other ones, but doesn't address everything.
Also, note, it is not the program content itself, it is the guests who appear on the content. I wonder why left-wingish guests would more likely prefer MSNBC or CNN given the alternatives?
Here's a diagram showing the distribution, which shows one CNN show further right than a Fox show, and while three are more left than 4 MSNBC shows, MSNBC has the extreme left wing of it. These are the 5 most popular shows on the network during the surveyed period. CNN Right Now ran for most of the surveyed period, while The O'Reilly Factor, famously, was cancelled partway through.
Further analysis of the article shows us both MSNBC and CNN competed in moving to the left, but they are roughly equivalent in leftyism (as defined in the survey). Here's the diagram tracking it, again, using their metric (which is based on how left-right the various congressional and other political guests were):
What this says is that for a period of time shortly after the election of Trump, CNN moved closer to the centre, and MSNBC moved *further* to the centre, before coming back after 2018. Specifically, CNN was slightly more lefty in the mornings, slightly more centre in the afternoon, and then caught up in primetime around the same time both went left, but MSNBC went further left in 2020.
This kinda shows the opposite, that MSNBC actually tacked harder centre than CNN did, but they both move in close lock-step. Of course, this particular report also shows the difference, and it shows that from 2012-2015 CNN was closer to Fox, then for about 4 years it was the opposite, then back the other way. So it has been since Zucker took over...about split down the middle by this one specific metric. And moved back BEFORE Zucker left.
Again, by the metric of what guests were on, without analyzing the policy discussion or questions proposed. It's fair to assume politicians are appearing on friendly shows, of course, but it's not actually analyzing the content of the shows, but the positions of the guests, so we can't go too far on that.
If they both moved left, then they did, but I don't think the difference in the post-Trump part of the curve is terribly meaningful. Polarization of guests caused the lurch rather than the content. Both lurched right in guests after Trump, then the other way in 2018. I wonder why this is. What could have happened in that year.
