Pop star Swift is becoming a factor in the US election campaign: Democrats are hoping for a huge fan base. On the left: an open thirst for Swift, a vocal advocate for women's and LGBTQ+ rights whose well-known views generally align with Democrats.

The State Department's Eras Tour-themed international travel checklist? That was good. The FBI's tweet, disguised in the aesthetic of Swift's album Speak Now, urging people with "information about a federal crime" to "speak now"? Not so good.
