Text in the video reads “Look What Marsha Made Her Do” before a cut to news clips about the surprise endorsement.

The pop star has stayed silent on her political views for years, and her endorsement of Bredesen via Instagram post sent shock waves through the political and celebrity worlds.

“As much as I have in the past and would like to continue voting for women in office, I cannot support Marsha Blackburn,” Swift wrote in her post, adding that Blackburn’s voting record “appalls and terrifies” her.

The post appeared to drive a major spike in voter registrations, with more than 65,000 people registering nationwide in the 24-hour period after her post.
