I don't think it has sunk in yet just how unpredictable virtually everything in Donald Trump's administration is going to be.
To begin with, the incoming tweeter-in-chief has taken positions on both sides of many issues. Maybe he has thought through a number of policies and maybe he hasn't, but either way we know almost nothing of his preferences beyond those that appear to be based on instinct (trade deals bad, Putin good).
And this is only the beginning.
Recent presidents have been fairly predictable because they were partisan. Their actions, including personnel choices, reflected the views of the majority coalition within their party. Even those White House staffers whom we think of as having close ties to the president (George Stephanopoulos for Bill Clinton, Karl Rove for George W. Bush, David Axelrod and David Plouffe for Barack Obama) had careers as Democratic or Republican campaign or governing professionals before their better-known connection was established. As such, they could be seen as partisan actors, not presidential loyalists, and were part of the process of constraining the president.
