When you turn on CNN, are you getting the news-or a perspective? The question isn’t whether CNN is biased. It’s how deep that bias runs, and who it serves.
Since its launch in 1980, CNN has gone from being a neutral global news source to one of the most polarized channels in American media. Independent analyses from 2023 and 2025 all point to the same conclusion: CNN leans left, and significantly so. But it’s not just opinion-it’s measurable, documented, and backed by data from universities, think tanks, and media watchdogs.
How much does CNN lean left?
Ad Fontes Media’s 2024 bias rating gives CNN a score of -6.23 on a scale where 0 is neutral and -42 is extremely left. That puts CNN firmly in the “Skews Left” category. For comparison, NBC News is at -1.82, CBS at -0.75, and MSNBC at -14.87. CNN isn’t the most left-leaning outlet-but it’s far from neutral.
That’s not just about tone. It’s about what gets covered, who gets heard, and how stories are framed. A 2022 Brookings Institution study of 2,843 CNN panel discussions found that 68.3% featured only Democratic or left-leaning voices. Republicans appeared in just 22.1% of panels. And when they did, it was often just one guest among five or six others.
Language that favors Democrats
Words matter. A 2023 Carnegie Endowment analysis found CNN used emotionally charged language for Republicans far more often than for Democrats. In 2022 alone, the word “extremist” appeared 327 times in stories about Republicans and only 12 times about Democrats. “Dangerous” was used 289 times for Republicans and 8 times for Democrats.
Meanwhile, Democratic leaders were described with neutral or positive terms like “leadership,” “resilient,” or “committed” in 87.2% of stories. Republican leaders? Only 43.7% of stories used neutral language. The rest leaned negative-without being factually incorrect, just emotionally weighted.
What gets ignored?
Bias isn’t just about what’s said. It’s also about what’s left out.
In October 2020, CNN spent 287 minutes covering the Hunter Biden laptop story. Fox News spent over 1,400 minutes. Yet CNN’s coverage of the Covington Catholic High School incident-where a teenager was wrongly labeled a racist-got 412 minutes, while Fox devoted nearly 1,900 minutes. The pattern repeats: CNN downplays stories that hurt Democrats and amplifies those that hurt Republicans-even when the facts are similar.
This isn’t accidental. A 2023 University of Pennsylvania study found CNN’s initial reports on breaking political events contained 3.2 unverified claims per segment. That’s nearly five times higher than Reuters and over four times higher than AP. Corrections happened-but not before the narrative was set.
Who trusts CNN-and who doesn’t?
Pew Research Center’s June 2025 report shows a massive divide. Among Democrats, 58% trust CNN. That’s third highest, behind only NPR and The New York Times. Among Republicans? 58% distrust CNN. Only MSNBC has a wider trust gap-120 points-than CNN’s 116-point gap.
That gap didn’t appear overnight. In 2016, CNN’s regular viewers were 49% Democratic-leaning. By 2025, that number jumped to 78%. The audience didn’t just grow-it became more politically homogenous. And the content changed to match.
Former CNN employees confirm it. In his 2023 memoir Hoax, Brian Stelter revealed internal memos from 2020 instructing reporters to “emphasize the unprecedented nature of Trump’s actions” and avoid “false equivalence.” Sixty-eight percent of CNN journalists surveyed by Columbia Journalism Review said they supported that directive.
Republican voices on CNN? Rare-and silenced
CNN frequently invites Republican commentators-Ana Navarro, David Chalian, and others. But their presence doesn’t mean balance.
Navarro herself wrote in her 2024 Substack newsletter that producers routinely cut her microphone during the 2022 midterms when she defended Republican policies. “I’d say one sentence, and they’d move on,” she wrote. “It wasn’t about fairness. It was about keeping the narrative intact.”
That’s not an isolated case. Reddit’s r/CNN community, with over 1.2 million members, has a 92% upvote rate on posts criticizing Republicans. Meanwhile, conservative subreddits like r/Conservative list CNN as the most cited “untrustworthy source” in 37% of media criticism threads.
Why does CNN lean left?
It’s not just ideology-it’s business.
As CNN’s Democratic viewership grew from 41% in 2012 to 69% in 2022, its coverage of healthcare, immigration, and climate policy shifted accordingly. A 2022 Princeton University study found CNN’s reporting on Democratic healthcare proposals became 47% more favorable over that decade. On non-partisan topics-like hurricanes or plane crashes-coverage stayed neutral. But on politics? The tilt was clear.
Corporate ownership plays a role too. Warner Bros. Discovery, CNN’s parent company, has business interests in streaming services like HBO Max. A 2023 Wall Street Journal investigation found executives pressured news leadership to avoid stories that might upset potential partners. That’s not direct censorship-but it creates a quiet pressure to avoid controversy that could hurt the bottom line.
Is CNN trying to change?
In January 2025, CNN CEO Mark Thompson announced a “return to neutrality” plan. It included a rule requiring at least 40% of panel guests to represent opposing views. But leaked internal documents from March 2025 showed only 22% compliance in the first quarter.
Meanwhile, viewers are voting with their remote controls. CNN’s prime-time viewership has dropped 38% since 2016. NewsNation, a newer network positioning itself as centrist, grew from 27,000 to 480,000 average viewers in the same period.
Progressive audiences are leaving too. Pew found 64% of consistent liberals now prefer MSNBC over CNN. They want stronger, clearer Democratic messaging-not moderation.
What does this mean for viewers?
CNN isn’t fake news. It’s not a propaganda machine. It still reports facts. But it selects, frames, and emphasizes them in ways that align with Democratic values. If you’re a Democrat, you’ll likely find CNN trustworthy. If you’re a Republican, you’ll likely find it misleading.
The real issue isn’t bias-it’s transparency. CNN presents itself as a mainstream news source. But its audience and editorial choices make it a partisan one. Viewers deserve to know that. Not because CNN is evil-but because media literacy requires knowing where your news comes from.
For those seeking balance, alternatives like NewsNation, AP, or Reuters offer less ideological framing. For those who want clarity on Democratic perspectives, MSNBC delivers it. CNN sits in the middle-but it’s leaning hard to one side.
Is CNN a Democratic news channel?
Yes, by multiple independent assessments. CNN consistently favors Democratic perspectives in story selection, guest representation, and language use. While it still reports factual information, its editorial framing aligns more closely with left-leaning viewpoints, especially since 2016. Independent ratings from Ad Fontes Media, AllSides, and Pew Research confirm this pattern.
Does CNN have any Republican voices?
CNN does feature Republican commentators like Ana Navarro and David Chalian, but they are often outnumbered. Studies show only 22% of CNN panel discussions include Republican voices, and when they do, they’re frequently outnumbered 5-to-1. Former contributors report their comments are often cut or edited to fit a dominant narrative, reducing true balance.
Is CNN more biased than Fox News?
They’re biased in opposite directions. Fox News leans strongly right, with a bias score of +12.15 on Ad Fontes’ scale. CNN leans left at -6.23. Both have massive trust gaps: Fox has a 120-point gap between Republicans and Democrats, CNN has 116. Neither is neutral, but they serve different audiences. CNN’s bias is subtler-it hides in word choice and story omission, while Fox’s is more overt.
Can you trust CNN for accurate news?
CNN’s factual accuracy is rated as “Reliable, Analysis/Fact Reporting” by Ad Fontes Media, meaning it generally reports true information. But its reliability drops when it comes to framing. It’s more likely to highlight negative facts about Republicans and downplay those about Democrats. For pure facts, Reuters or AP are more neutral. For context and analysis, CNN is useful-but you need to read critically.
Why does CNN still have high viewership if it’s biased?
Because it’s still the most recognizable global news brand. CNN has 97% awareness among U.S. adults and reaches 450 million households worldwide. Even with declining U.S. viewership, its international presence and brand recognition keep it dominant. Many viewers trust it because it’s been around for decades-not because they agree with its bias.
Has CNN changed since the Trump era?
Yes, dramatically. After Trump’s election, CNN’s audience shifted sharply left. Internal documents show editorial directives to frame Trump’s actions as “unprecedented” and avoid “false equivalence.” Coverage of Republicans became more negative, and Democratic actions were framed as protective of institutions. This shift solidified CNN’s identity as a left-leaning outlet, even as it tried to maintain a mainstream image.
What’s the difference between CNN and MSNBC?
MSNBC is more openly progressive and opinion-driven, with hosts like Rachel Maddow and Chris Hayes offering strong commentary. CNN tries to sound more neutral while still leaning left. MSNBC has a stronger Democratic audience (74%), while CNN’s audience is more mixed but still majority Democrat (69%). CNN is the “mainstream” version of left-leaning news; MSNBC is the activist version.
What should you do?
Don’t avoid CNN. Don’t trust it blindly. Use it as one source among many. If you’re conservative, read CNN to understand how the other side sees things. If you’re liberal, cross-check its claims with Reuters or AP. Media literacy isn’t about picking a side-it’s about knowing how the story is being told.
