Since Taylor Swift announced her endorsement of Vice President Kamala Harris on the night of the debate with former President Donald Trump, publications from NBC to Fox have been debating what it might mean for Harris’ campaign and the outcome of November’s election.

An Instagram post from Sept. 10 shows the pop star posing with a fluffy cat in her arms—a direct reference to JD Vance’s quip deriding single and childless women. Before signing the post, “With love and hope, Taylor Swift, Childless Cat Lady,” Swift told followers that she plans to vote for Harris “because she fights for the rights and causes I believe need a warrior to champion them. I think she is a steady-handed, gifted leader and I believe we can accomplish so much more in this country if we are led by calm and not chaos.”

Ms. spoke with contributing editor and scholar Dr. Janell Hobson about about what the endorsement might mean.
