Myriad baseless rumors emerged on social media — everything from claims that Swift has played a part in Pentagon psychological operations to the idea that she and her two-time Super Bowl champion boyfriend are key assets in a secret plot to help President Biden get reelected in 2024. Another variant: That the Chiefs’ success was rigged as part of the plan for the game on Feb. 11 in Las Vegas.

Political and media figures on the right, including former Republican presidential candidate Vivek Ramaswamy, political activist Laura Loomer and One America News Network host Alison Steinberg, have amplified the allegations.

Mike Crispi, a major pro-Trump broadcast personality, said on X, formerly Twitter, that “The NFL is totally RIGGED for the Kansas City Chiefs, Taylor Swift, Mr. Pfizer (Travis Kelce). All to spread DEMOCRAT PROPAGANDA. Calling it now: KC wins, goes to Super Bowl, Swift comes out at the halftime show and ‘endorses’ Joe Biden with Kelce at midfield. It’s all been an op since day one.”

Wasim Khaled, the CEO of Blackbird AI, a company that monitors disinformation, told CBS News these conspiracy-minded narratives “typically start to simmer [in] the dark web, and kind of the fringes and underbelly of the internet. … And then at some point, they gain traction around other events that are gaining people’s attention. In this case, it was the Super Bowl.”

In his company’s tracking, he said, “We really see that spread, and we can really see a narrative evolve grow, and become more harmful over time.”

The claims are ludicrous and may well reflect the fear on the right that someone as famous as Swift, whose landmark Eras Tour is the first tour to cross the billion-dollar mark, could indeed influence the presidential race should she urge her legion of fans in one direction.

How much would a Swift endorsement help Biden?

The potency of the impact is less clear. In Swift’s case, there is some proof that she can at minimum generate more voter registration.

In September, Swift posted a short message on her Instagram account encouraging her 272 million followers to register to vote. The post led to more than 35,000 registrations on the nonpartisan nonprofit Vote.org.

Swift’s massive fan base gives her a powerful voice. An SSRS poll conducted in October 2023 found that about 6 in 10 U.S. adults called themselves at least casual fans of the singer, with 8% saying they’re big fans. The poll also found that 8 in 10 U.S. adults said they’d heard of her relationship with Kelce and the majority of those familiar with it considered it a real relationship, rather than a publicity stunt.

“Pop culture people identify with this stuff, they pay attention to it. And that’s what moves politics now. It’s attention and identity,” said Joel Penney, an associate professor at Montclair State University whose research includes the intersection of politics and pop culture. Indeed, Donald Trump’s improbable march to the presidency in 2016 was propelled in part from the celebrity he gained as a reality television star.

But the false claims about Swift are of such an extreme nature that they will test the limits of how potent a conspiracy theory can be.

Penney sees the recent deluge of posts aimed at Swift as an attempt to preemptively blunt her impact by discrediting her.

Penney said Swift’s influence could prove a difficult force to contend with, especially if she publicly supports Biden, as she did in the 2020 race.

The attacks on Swift could also galvanize young voters who want to rally around her.

“Young people are fighting their political battles through a language drawn from pop culture,” said Henry Jenkins, a professor at the University of Southern California who also studies politics and pop culture. “That’s what connects them. That’s what they’re engaged with.”

Apparent leanings of Swift and Kelce

Both Swift and Kelce have made public statements about politics and other issues that put them at odds with the far-right.

Swift broke her long-standing refusal to discuss her political views in 2018 when she announced in an Instagram post that she would be voting for Tennessee’s Democratic Senate candidate Phil Bredesen and Democratic House incumbent Rep. Jim Cooper. She also slammed then-U.S. Rep. Marsha Blackburn, the Republican candidate, citing Blackburn’s opposition to certain LGBTQ+ rights and her vote against the reauthorization of the Violence Against Women Act in 2013. Blackburn won election to the Senate.

In 2020, Swift endorsed Mr. Biden and Vice President Kamala Harris in an interview with V Magazine, noting that “under their leadership, I believe America has a chance to start the healing process it so desperately needs.”

Kelce faced criticism in September for appearing in an ad promoting the double dose of the flu and COVID-19 vaccines, as recommended by the Centers for Disease Control and Prevention. The ad was part of a partnership with Pfizer, the pharmaceutical company that developed a vaccine in response to the pandemic and has since become a common mark for anti-vaccine activists and conspiracy theorists.

Pop culture figures and the industry that surround them have been enmeshed in political campaigns long before the duo some fans refer to as Swelce.

Former President Bill Clinton first appeared on MTV during his 1992 campaign while he was still governor of Arkansas. Major stars including Johnny Cash, Mary Tyler Moore and Willie Nelson endorsed former President Jimmy Carter more than 40 years ago when he made his second run for the White House. Ronald Reagan got his start in politics after a career as an actor.

“That question of, does this stuff work in pop culture? It absolutely can,” Penney said. “And it does. And history has shown that.”
