In a post on Instagram, Swift told her over 280 million followers that she will vote for the U.S. vice president in the November 5 election, the biggest celebrity endorsement yet for Harris. Polls show the race is essentially tied between the two candidates.

“I will be casting my vote for Kamala Harris and Tim Walz in the 2024 Presidential Election. I'm voting for @kamalaharris because she fights for the rights and causes I believe need a warrior to champion them,” Swift said in her post.

Swift was pictured with her cat in the post, which she signed as “childless cat lady,” in a dig at Trump's running mate JD Vance, who in a 2021 interview called some Democrats “a bunch of childless cat ladies,” suggesting they were incompetent in relationships and had a nihilistic outlook.

Swift has supported Democrats in the past and backed President Joe Biden in 2020. Her endorsement is the latest for Harris from the entertainment industry. Many Hollywood actors, producers and filmmakers have said they viewed Harris, a native Californian, as their hometown candidate.

Some commentators have raised concerns about the U.S.’s emphasis on celebrity culture, reflecting the lack of depth of political engagement. Some have suggested that celebrity endorsements can overshadow more nuanced policy discussions, leading to a superficial understanding of complex issues.
