Pop music luminary Taylor Swift's decision to wade into electoral politics for the first time on Sunday has driven a spike in online voter registration, particularly among young people, according to the website Vote.org.

The nonprofit site, which helps people register online, reported 240,000 new registrations since Swift posted a message on Instagram endorsing two Democratic candidates in her home state of Tennessee and urging people to register.

By comparison, the site recorded 57,000 new registrations in all of August and 190,000 last month. About 102,000 of the registrations since Sunday were among voters between 18 and 29 years old, an increase that the site said was likely prompted by Swift's post.
