Taylor Swift has energized a key voting bloc in Tennessee.

Vote.org confirmed Tuesday that the organization experienced a spike of about 64,000 people between the ages of 18 and 29 years old since Swift took to social media to endorse Democrats running for election in the traditionally red state.

The famously apolitical pop star posted on Instagram Sunday, endorsing two Democratic candidates running in this year's midterm elections in her home state of Tennessee: Phil Bredesen and Rep. Jim Cooper.

Bredesen is running against Republican Rep. Marsha Blackburn in the state’s U.S. Senate race.

In her post, Swift said she could not bring herself to vote for Blackburn because “her voting record in Congress appalls and terrifies me.”

“We're especially happy to see that because we know voting is habit-forming,” said Kamari Guthrie, a spokesperson for Vote.org, told the Washington Examiner. “Statistically, a young person who votes in 2018 is 55 percent more likely to vote again in 2020.”

President Trump won Tennessee by 26 points in 2016.
