No one cares about this. It reeks of desperation. Trump shows up by himself and gets 1000's of fans. The Dems have to trot out celebrities, which do nothing to help them in the long run. Also Eminem? Very few Blacks listen to him, he's Beastie Boys status in that world. It won't help with Latinos or Whites either.
This was for elderly White people, who think Eminem is a get.
50 Cent is low key Trump, as are a bunch of other rappers.
