What did the autopsy really reveal? I would call for an independent autopsy. Any indications of a struggle will suggest Tafari Campbell was murdered.
IMO: Michelle will get the Democrat nomination.
The possibility exists that the death of Campbell and Obama’s injuries, including the black eye, may have been warning shots to Obama and his minions not to promote Michelle as a Presidential candidate. Assuming Biden does not rum for a second term, the Deep State may have their candidate, maybe Gavin Newsom or Gretchen Whitmer, selected in that event. Given that Obama is probably running the Biden Administration behind the scenes and the numerous failures, the powers that be do not want a fourth term for Obama, with Michelle as a new sock pupper.
