6% of Americans declare themselves a “fan” of the singer; and up to a third of people call themselves at least “somewhat of a fan,” according to YouGov surveys. Taylor Swift said in 2020 that she would vote for Joe Biden, which obviously puts her closer to the Democrats, but that doesn't stop her from having Republican fans.
Among her fans there would be almost as many Donald Trump voters as Biden voters in 2020. Half of those surveyed claim to not know if Taylor Swift is a Republican or a Democrat.
