Republican presidential candidate Ben Carson launched his campaign with a gospel cover of Eminem’s “Lose Yourself.” Carson and Eminem are both from Detroit, so the rapper’s high-energy anthem seems a fitting choice. Carson, NME reports, is a retired pediatric neurosurgeon, and is the Republican party’s first black candidate in next year’s election. His claim to fame is performing the first successful separation surgery on a set of twins conjoined at the head.
