It's often said of American politics that it's a huge juggernaut and the president can change the direction by two or three degrees in either direction, but not much more. In fact, I think the president's power is limited, much more than the prime minister in England.

Dickens is a much misunderstood and mis-approached writer, in that he tends to be read, particularly in the twentieth century, as a social commentator - like the great Victorians, a realist in his way.
