NASHVILLE, Tenn. (AP) — Presidential candidate Pete Buttigieg held a rally in Tennessee as voters were casting ballots for president in South Carolina.

Buttigieg, the former Democratic mayor of South Bend, Indiana, spoke to a crowd of several hundred on Saturday afternoon and took questions at Public Square Park.

“I’m a red state Democrat too,” he told the crowd, emphasizing his centrist Democrat platform. “We've got to campaign everywhere.”

Buttigieg took a jab at Democratic front-runner Bernie Sanders and his fervent online followers.

“The best way to build a majority that will defeat Donald Trump is to call people in, not to call people names online,” he said, standing on a raised stage.

Buttigieg had a strong finish in Iowa and was third behind Sanders and former vice president Joe Biden in Nevada. He has asked supporters to help him raise $13 million to be competitive through Super Tuesday, when 14 states including Tennessee hold primaries.
