Nine days after former President Donald J. Trump falsely claimed to accept an endorsement from the pop superstar Taylor Swift, thousands of Swift fans, including some high-profile cultural and political figures, gathered on a video call with the goal of ensuring his defeat.
They shared their favorite Swift songs. They quoted their favorite Swift lines. And then they assailed Mr. Trump’s political agenda as a threat to women.
One fan, the singer Carole King, sang Ms. Swift’s song “Shake It Off.” Another, Senator Elizabeth Warren, Democrat of Massachusetts, described Mr. Trump as a bully who was “trying to claw us back into the dark days.”
Senator Kirsten Gillibrand, a New York Democrat who attended two concerts on Ms. Swift’s Eras Tour, made a series of jokes at Mr. Trump’s expense that played on the singer’s lyrics.
They all were gathered on Tuesday under the banner of Swifties for Kamala, a group that is not officially affiliated with Vice President Kamala Harris or Ms. Swift — who has not publicly endorsed a candidate in the election — but that is seeking to deploy the intensity of Ms. Swift’s vast fan base in support of Ms. Harris’s bid for the White House.
“For me, Kamala is really a relaxing thought,” Emerald Medrano, 22, a founder of the group, said on the call, alluding to the singer’s lyrics in the song “Karma.”
The early returns from the group’s organizing call on Tuesday — which lasted two hours and was joined by about 34,000 people across Zoom, YouTube and TikTok — have been promising, the group said on Friday: $130,000 raised for the Harris campaign over four days. But organizers hope the effort will have a potentially more powerful effect, reminding young people in swing states to register to vote.
“Swifties just never do anything small,” Irene Kim, 29, another founder of the group, said in an interview on Friday.
The Trump campaign responded by asserting that it was the true campaign for Swifties.
“As Kamala Harris continues to lie about her values and policies, voters will realize they knew she was trouble when she walked in,” a spokesman for Mr. Trump, Steven Cheung, said in a statement that lifted lyrics from Ms. Swift’s songs “I Knew You Were Trouble” and “Bad Blood.” “Americans have bad blood with Kamala Harris’ radical agenda, and that is why Swifties for Trump is a movement that grows bigger every single day.”
It is not clear that there is any organized Swifties for Trump group, though Mr. Trump has shared what appear to be A.I.-generated images of women wearing T-shirts with that label.
Ms. Swift holds huge sway on social media, logging more than 280 million followers on Instagram alone. Many of those fans carefully dissect each of her public statements, and she is viewed as a rare celebrity whose endorsement might move a significant number of voters to the polls.
