Barack Obama is a Bruce Springsteen fan. In a recent interview with Rolling Stone, Obama said, "Not only do I love Bruce's music, I just love him as a person. He is a guy who has never lost track of his roots, who knows who he is, who has never put on a front." He added that, when speaking to the singer, he addressed him by his moniker the Boss. "You've got to," Obama said.
Bruce (yes, we are on a first-name basis) endorsed Obama in April.
