As Jon Stewart wraps up 16 years of hosting The Daily Show Thursday night, one thing is certain: We’re all dumber for his tenure.

Under Stewart, The Daily Show became must-see TV for a segment of the population who considers the mocking of political opponents and their positions to be appropriate discourse, and worse—an acceptable method of news-intake. A 2014 Brookings Institution study found that more people trusted The Daily Show than MSNBC for news.

Headlines such as “Jon Stewart destroys Glenn Beck,” “Jon Stewart demolishes Megyn Kelly and Fox,” “Jon Stewart eviscerates CNN,” “Jon Stewart crushes Dick Cheney” became standard for Stewart’s viral videos. He would pick a target, usually a conservative and frequently a Fox News personality, and would proceed to “destroy,” “demolish,” “eviscerate,” “crush,” and sometimes flat-out “shred” them.

Like a musician lecturing into a microphone onstage, Stewart only permitted one-way mockery. When anyone questioned his opinions and methods, he would say his show was just comedy. In 2013 when it seemed that Stewart was mocking the Obamacare rollout a little too often, he got pushback from his liberal followers. Stewart was quick to point out it was just equal-opportunity joking, and he wasn’t taking a position. He, of course, did not offer similar explanations when hammering President George W. Bush’s policies.

In a famous exchange on the CNN debate show Crossfire in 2004, Stewart called Republican Tucker Carlson and Democrat Paul Begala “partisan hacks” who poisoned the discourse. When Carlson pointed out that Stewart had given a softball interview to John Kerry, whom Stewart admitted voting for, Stewart blew up and said, “You’re on CNN! The show that leads into me is puppets making crank phone calls! What is wrong with you?”

Yet Stewart was exactly the kind of partisan hack he eviscerated. Politico recently reported that not only had Stewart met in secret with President Barack Obama right before big stories were set to hit, but Obama’s aides had also worked with Daily Show writers so that their side of the story was well-represented.

That work-the-umps strategy also involved the president, who used his two Oval Office meetings with Stewart as a chance to sell the administration’s ideas. At the 2011 sit-down, [Obama aide] Goolsbee said, the president wanted to counter his critics on the left and lay the groundwork for his 2012 reelection campaign. The White House itself was quite interested in at least explaining its side of the story to Jon Stewart,” Goolsbee said, “up to and including the president.”

As Kyle Smith noted in the New York Post, “Remember when, under a Republican president, it was the duty of all comedians to be the loyal opposition, to speak truth to power? Stewart does the opposite.”

When your writers are taking tips on how to joke about politics from the White House, it’s safe to say it doesn’t matter that your show is on Comedy Central. It’s a bad sign for the country that any percentage of people got their news from this compromised comedian. Goodbye Jon Stewart’s Daily Show. Good riddance.
