She said in a recent interview with DPA that her upcoming music will feature political messages.

"I definitely think there are political undertones in the new music I made,” Swift said. “I’m not planning to stop encouraging young people to vote and to try to get them to talk about what’s going on in our country. I think that’s one of the most important things I could do.”

On June 1, the first day of Pride Month, Swift posted a letter on her social media accounts that she wrote to Tennessee state Senator Lamar Alexander urging him to vote for the Equality Act, which protects LGBTQ+ people from discrimination.
