Vermont Senator Bernie Sanders is making an unusual promise to voters if he’s elected. Appearing on the “Joe Rogan Experience” podcast, Sanders promised to go back on the show after he was president to announce the existence of space aliens — if they exist.

Rogan: “If you got into the office and you found out something about aliens, if you found out something about UFOs, would you let us know?”

Sanders: “Well I tell you, my wife would demand I let you know.”

Rogan: “Is your wife a UFO nut?”

Sanders: “No, she’s not a UFO nut. She goes, ‘Bernie, What is going on do you know? Do you have any access?’”

Rogan: “You don’t have any access? You’ll let us know though?”

Sanders: “Alright, we’ll announce it on the show. How’s that?”

That would suit Rogan fine. He’s been called a “dark web intellectual,” a man who entertains the most rancid, kooky, outside-the-box thinking guests and gives them a national forum for them to spout. From alt-right to antifa, Rogan doesn’t care about a guest’s politics as long as they’re controversial.

His show is audio clickbait and Sanders bots eat it up.

The Joe Rogan Experience is a good, friendly format for Sanders—his podcasts are long, he rarely cuts off his guests, and he has a tendency to let them talk about whatever they want to talk about, which in some cases has allowed bad men to amplify their ideas to his massive audience unchallenged. Tuesday, Sanders handled himself well, calmly laying out his case against the billionaire class, potential political campaign reforms he’d be in favor of, and explaining why, in his view, the United States continues to lag behind the rest of the world on education and healthcare. Without the debate limitations of having to talk in 15-second soundbites, Sanders shone. And hey, now we have a campaign promise.

Sanders won’t find anything of note about aliens that most of us don’t already know. President Clinton swears he looked into the Area 51 matter and did not find any aliens. Jimmy Carer claims he actually saw a UFO once. This, of course, does not deter the enthusiasts who simply point out that presidents are probably out of the loop and couldn’t be trusted with the sacred scrolls of… er… the information about alien visitation that is absolutely for certain somewhere in that manure pile. We only have to keep looking.

What Sanders will find are more mysteries. Recently released files from the U.S. Navy show some incredible encounters with aircraft capable of impossible maneuvers at unbelievable speeds. Illusion or real? Most of us would certainly like to know. If Sanders could be more forthcoming about what the government actually does know about possible alien visitation, it would be a step forward.
