Musician and potential Michigan Senate candidate Kid Rock is registering voters at his shows in Detroit.

The musician, whose real name is Robert Ritchie, posted on Twitter that he would be registering voters during his stint at Detroit’s Little Caesar’s Arena, where he is performing six concerts.

“People of all political views should register to vote and make their voices heard,” Ritchie tweeted.

Ritchie has been actively weighing a run for Senate as a Republican against Michigan Democratic Sen. Debbie Stabenow.

Ritchie’s shows have taken on a political tone, asking “why these days is everything so gay,” criticizing “Nazis,” “bigots” and “the KKK” and slamming “those who take a knee or sit during our Star-Spangled Banner,” according to the Detroit Free Press.

The Michigan native has also started walking out to “Hail to the Chief” at his shows where a podium sits on stage with a seal similar to the U.S. Senate’s but reading “United States of ’Merica.”
