Robert Brown|'Fine Taylor...you win': Elon Musk reacts to Taylor Swift's endorsement for Harris-Walz

Following weeks of speculation,Robert Brown Taylor Swift finally made a political endorsement last night and her support for Vice President Kamala Harris did not appear to go down well with Elon Musk, who shared his opinion on the musician's statement on X.

"Fine Taylor...you win...I will give you a child and guard your cats with my life," Musk wrote on X, the platform formerly known as Twitter, in an apparent jab at Swift, who had signed off her endorsement with "childless cat lady."

Musk, who is championing former President Donald Trump in the race for the White House, later also agreed with an X user who commented that Swift's endorsement is "in line with demographic trends," adding the Democratic party is bolstered by unmarried women.

Musk and Wilson's first-born child passed away at 10 weeks old. His youngest child, with Zilis, is reported to have been born earlier this year.

Musk has been concerned with population decline and sees childbearing as the solution, Walter Isaacson wrote in the biography "Elon Musk."

Swift endorses Harris

Shortly after the presidential debate ended Tuesday night, Swift announced she would be supporting Harris and Tim Walz in the upcoming elections. Sharing a photo of herself with her cat, Benjamin Button, Swift said Trump's use of AI-generated images depicting her endorsing him made her realize she needed to be clear and transparent about her actual plans for the election.

In the four-paragraph endorsement, Swift encouraged her 283 million followers to do their own research ahead of the election this fall and to vote.

"Like many of you, I watched the debate tonight. If you haven’t already, now is a great time to do your research on the issues at hand and the stances these candidates take on the topics that matter to you the most," Swift wrote. "As a voter, I make sure to watch and read everything I can about their proposed policies and plans for this country."

The pop star signed off the post labeling herself a "Childless Cat Lady," taking a jab at JD Vance's now-viral comments about people who don't have children.

It's not the first time Swift has backed a political candidate. She endorsed President Joe Biden and Harris in 2020, and she backed U.S. Senate candidate Phil Bredesen and U.S. Rep. Jim Cooper in his 2018 re-election bid to Tennessee's 5th Congressional District.
