I don't watch cable news that often. But from what I can tell, Tucker Carlson is one of the FEW that actually invites real life actual journalists on his show like Glenn Greenwald, Matt Taibi, and Aaron Mate.
He is one of the few if not the only mainstream tv news anchor that openly rails against the federal governments abuses of the law and attacks on the first amendment, one of the few if not the only that has dedicated prime time segments to demanding the end of the persecution of Julian Assange, one of the few if not the only that exposed all the lies of the US govt in terms of the Syrian war, one of the few if not the only that has called out the US govt for it's fanning the flames of potential nuclear war in Ukraine, and one of the few that openly called into question the damage control narrative of the mainstream media that Russia blew up it's own pipeline in Germany and one of the few that actually ran segments on Sy Hersh's bombshell article which reports that the US blew up the NordStream 2 pipeline. Sy Hersh is only inarguably the greatest investigative journalist in the history of the United States. He's only broken more bombshell stories than oh- anyone in the history of American journalism.
These tv news anchors aren't journalists...they are actors whose main function is to manufacture consent and spread propaganda and do narrative control for specific sets of the elites/ruling class. My guess is Tucker got himself into too much trouble for actually telling the truth from time to time.
He had by far the highest rated show on cable news, triple the ratings of basically every other news show on cable tv, and not to mention he had the highest ratings for the key demo 25-44 among all people in that age group- including registered democrats. Fox stock crashed $700 million since the announcement of his leaving. They just made a huge mistake imo. He was the biggest draw they had- now they'll be just like CNN/MSNBC and have basically no one watch their channel.
