Could the "Taylor Swift effect" swing the Tennessee Senate race?

That's what Wall Street Journal political editor Jeanne Cummings wondered on "Shepard Smith Reporting" on Thursday when she was asked if there's a midterm race that will surprise people.

Swift issued a rare political endorsement last month, declaring her support for Democratic Senate candidate and former Tennessee Gov. Phil Bredesen over his Republican rival Rep. Marsha Blackburn.

Recent polling shows Bredesen trailing Blackburn by at least several points, but Cummings believes Swift's massive social media following could come into play.

"She early-voted, she took a picture of herself early-voting, put it on her Twitter feed, put it out there on Instagram. And now when young people are voting down, they send their picture to her and Taylor Swift is putting it out on her social media," Cummings said. "So they're being seen by millions of people. Even if you don't care about politics, for some of them it's just going to be pretty cool to get on Taylor Swift's Instagram and to get a 'way to go' from Taylor Swift."

"So she could play a role in this like we have not seen from celebrities, given the social media aspect," Cummings said.

Shepard Smith remarked that it will be interesting to follow the "Taylor Swift effect" in the Volunteer State.
