Trump's likely cabinet selections are in the press.[1]
Treasury - probably Steven Mnuchin, another Goldman Sachs guy. Trump may not be as anti Wall Street as he said he was.
State - Bob Corker (Senate foreign relations chair) or Newt Gingrich. Both are long-time Washington insiders.
Defense - about four candidates, mostly long-time Washington insiders.
Attorney General - Rudy Guilani, probably. As a prosecutor, he took down the New York Mafia, so he's qualified for the job.
Old, white, Republican insiders, all of them. Mnuchin is the only one below retirement age.
