After Taylor Swift's mega endorsement, it took just one hour for the Harris-Walz campaign to start selling friendship bracelets

• The Harris-Walz campaign has wasted no time — it now has Taylor Swift-inspired merch.
• Shortly after Taylor Swift endorsed them, they started selling friendship bracelets inspired by her.
• The website said: "Are you ready for it? Harris-Walz friendship bracelets are here!"

It took the Harris-Walz campaign just an hour after receiving Taylor Swift's mega endorsement to start selling friendship bracelets inspired by the singer.

Shortly after the ABC News presidential debate between Vice President Kamala Harris and former President Donald Trump ended, the superstar posted a ringing endorsement of the duo to Instagram.

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

About an hour after the Instagram post went live, Harris' campaign merchandise website started selling "Harris-Walz Friendship Bracelets" priced at $20 for a pack of two.

The adjustable, waterproof bracelets are made with blue and black thread and cream-colored clay beads that spell out the words "Harris Walz 24."

"Are you ready for it? Harris-Walz friendship bracelets are here!" the product description read, referring to Swift's popular song "…Ready For It?" from her 2017 "reputation" album.

Friendship bracelets have become a popular addition to "The Eras Tour" concert outfits. They are inspired by lyrics from Swift's "You're On Your Own, Kid," a song from her 2022 "Midnights" album.

It is now a tradition for concertgoers to trade the handmade bracelets with other showgoers.

The campaign's X account, KamalaHQ, was quick to whip up an edit of Swift's endorsement as well.

The X post made shortly after midnight on Tuesday said, "Kamala is ready for it. " It then transitioned into a screenshot of Swift's endorsement post with the same song as the soundtrack.

When asked about the high-profile endorsement in an interview with MSNBC, Harris' running mate, Gov. Tim Walz, said: "I am incredibly grateful, first of all, to Taylor Swift."

"I say that also as a cat owner, a fellow cat owner," he said. "Look, Swifties, you heard it, you know that it's there."

"That was eloquent, and it was clear, and that's the type of courage we need in America to stand up," Walz added.

The campaign has put a lot of work into its merchandise leading up to the November elections, from appealing to Gen Z voters with a camo hat reminiscent of Chappell Roan tour merchandise to collaborating with the country's top fashion designers like Vera Wang and Tory Burch for its "Designers for Democracy" collection.

It's also leaned into younger, Gen Z-trend-driven messaging on social media, complete with references to Charli XCX's "brat" summer.

Representatives of Swift and the Harris-Walz campaign did not respond to a request for comment from Business Insider, sent outside business hours.
