I don't think the appointments are all settled, yet, but I agree that the list above is not representative of the nation. However, I think we should all have expected this. Trump is a businessman, who aims to choose the best person for the job, as long as he's on the same page as the boss. He's not a professional politician, conditioned to be sensitive to the wishes of his constituents. No US voter should be surprised - or even disappointed - if this elected leopard doesn't change his spots overnight.
The alternative media - which is the only reliable source of political news these days - thinks that two woman will be tapped for the Cabinet - Education and Veterans' Affairs. No Black-Americans, though I have also read that he offered Health to Dr Carson, who refused it. We'll have to wait till he's actually sworn in before we get the full list. And there's still a fair chance that he won't even become President!
