Only exception is foreign policy, where they have a pretty free hand to screw things up.

There’s lots of brash talk now about what will happen next week and what policies will
be put in place. I suspect that not much will actually happen because of bureaucratic inertia and the difficulty of getting things through Congress.

So why doesn’t anyone ever talk about how bad a president Andrew Johnson was? He was at odds with Congress from
the start, and they tried to restrain him as best they could (including the Tenure of Office Act). But it was very hard to check him.
