Singer Taylor Swift urged her followers to participate in early voting, which opened Wednesday in Tennessee where Swift will be voting in the 2018 midterm elections.

"Something I wish I knew about when I was 18 and voting for the first time: EARLY VOTING. It makes it so quick and easy to go and cast your vote before November 6," Swift wrote in an Instagram post Wednesday. "Early voting starts TODAY in Tennessee and goes to Nov 1. You can check out your state’s early voting dates at the link in my bio."

Earlier this month, Swift blasted Rep. Marsha Blackburn, R-Tenn., who is running for Senate in Tennessee against Democratic candidate and former governor of Tennessee, Phil Bredesen. Swift said she would cast her ballot for Bredesen and Rep. Jim Cooper, also a Democrat.

"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 on Instagram. "Her voting record in Congress appalls and terrifies me."

Swift’s support for early voting coincides with a video released Wednesday featuring former President Barack Obama urging Americans to vote early, something he equated to compared to going to a “private Jay-Z/Beyonce concert, just without Jay-Z and Beyonce.”

Residents of 37 states and the District of Columbia can vote early.
