WASHINGTON — The 10 Democrats who didn’t qualify for Thursday’s debate are doing everything they can — bad jokes and all — to keep the spotlight on themselves.

For Montana Gov. Steve Bullock, that meant trying to tickle voters’ funny bones.

Bullock penned a BuzzFeed listicle featuring cringers like: “The mama buffalo dropped her son off at school. What did she say?” ‘Bison!’”

His spokeswoman Galia Slayen said that with such a large Democratic field, “you stand out by playing to your strengths — in this case, that means wowing the voters and the press corps alike with the kinds of classic zingers that can only come from a father of three.”

And on debate day, he’ll try winning voters over with booze.

In the run-up to the debate Thursday, Bullock will campaign in Iowa alongside Christie Vilsack, whose husband was the state’s former governor. They’ll be hitting up a brewery and a winery in one day.

Afterward, Bullock will “drink with staff at a bar and play games during the actual debate.”

Instead of dad jokes, Rep. Tim Ryan (D-Ohio) “dropped an album” this week. “Really,” he wrote in a tweet as he showed off the 10 “tracks” he uploaded to Spotify. There’s no musical accompaniment. Instead, the songs are just Ryan’s voice, giving his take on subjects like “regenerative agriculture” and “new industrial policy.”

Spokesman Peter Mellinger said Ryan wanted to pair campaign stops with “digital content that resonates, is authentic and is easily consumable and shareable.”

“Do you ride the bus to work? Press pause on your favorite podcast one morning and learn about Tim’s vision,” Mellinger said.

Ryan will also be appearing IRL, as the kids call it, Thursday night as the other Democrats debate. He’ll speak at his alma mater, the UNH Law School in Concord, New Hampshire.

Marianne Williamson is going back to her roots too. She’ll be in the city where she launched her campaign — Los Angeles — to hold a debate watch party with supporters at the Writers Guild of America’s headquarters in Beverly Hills. And for fans everywhere, she’ll be livestreaming her take on the debate from that venue once it’s a wrap.

Former Maryland Rep. John Delaney, whose moderate message hasn’t resonated yet, plans to take it to a Fox News set. A campaign aide told The Post that he’s due to appear on “Special Report with Bret Baier” in the hours preceding the debate.

For billionaire Tom Steyer, who qualified for the fourth debate in October, he’s treating Thursday as business as usual, making two stops in Iowa, his campaign noted. Former Rep. Joe Sestak is campaigning too, concluding a five-day trip to New Hampshire on Thursday.

Rep. Tulsi Gabbard (D-Hawaii) and Sen. Michael Bennet (D-Colo.) have day jobs, of course, and Congress returned from August recess this week. Bennet, though, tried to get a little bit of media attention Tuesday by officially opening his campaign headquarters in Lakewood, Colorado.

The mayors who are polling below Mayor Pete Buttigieg are in their respective cities.

Miramar, Florida, Mayor Wayne Messam — yes, he’s still running — attended a 9/11 memorial ceremony yesterday. Multiple emails to his campaign spokesperson went unreturned about debate plans.

And Mayor Bill de Blasio will do a SIRIUSXM POTUS radio hit Thursday morning. He’ll be watching the debate from New York, his campaign spokeswoman said.
