Taylor Swift — the pop star who notably has strayed from politics — broke that silence on Sunday, writing on Instagram that she'll be voting for Tennessee Democrats in the midterm elections.

Swift, 28, slammed Republican Senate candidate Marsha Blackburn in an Instagram post.

"As much as I have in the past and would like to continue voting for women in office, I cannot support Marsha Blackburn," Swift told her 112 million Instagram followers. "Her voting record in Congress appalls and terrifies me."

Swift said the congresswoman "voted against equal pay for women. She voted against the Reauthorization of the Violence Against Women Act, which attempts to protect women from domestic violence, stalking, and date rape. She believes businesses have a right to refuse service to gay couples. She also believes they should not have the right to marry."

"These are not MY Tennessee values," the "Fearless" singer said online.

Swift concluded she'll be voting for Democrat Phil Bredesen for the Senate, and also for Rep. Jim Cooper, a Democrat who's running for re-election.

Bredesen quickly thanked Swift for her support on Twitter, writing he's "honored" by support from her and "that of so many Tennesseans who are ready to put aside the partisan shouting and get things done."

Blackburn's campaign did not immediately respond to Fox News' request for comment. A recent Fox News Poll found Blackburn was ahead of Bredesen 48 percent-43 percent, which was inside the poll's margin of error.

Many fans of Swift, who reportedly owns two properties in Nashville, in addition to several other homes throughout the U.S., have urged the international star to voice her political views — particularly to denounce President Trump.

She's long stayed quiet on her beliefs, but, in March, Swift wrote in an Instagram post that she donated to the March for Our Lives campaign in support of gun reform.

In July, it was rumored on Capitol Hill that Swift was scheduled to make an appearance at the Russell Senate Office Building, but she didn't show.

In her post Sunday, Swift acknowledged that many people "may never find a candidate or party with whom we agree 100% on every issue, but we have to vote anyway."

"So many intelligent, thoughtful, self-possessed people have turned 18 in the past two years and now have the right and privilege to make their vote count," she wrote, urging her followers to "educate" themselves on the upcoming elections.
