What is the setting in the novel, Hope Never Dies: An Obama Biden Mystery?

The United States of America is the novel's primary broad-strokes setting, even though the action of the narrative does not move beyond the boundaries around two particular locations in the country - Delaware and Washington D.C. The reason this setting is important is more political and cultural than geographical: the novel features a pair of characters, Barack Obama and Joe Biden, whose political careers, range of experiences, public personas and reputations (in short, their fundamental identities) are defined by their having been America's leaders, with everything that that involves - including celebrity status, remarkable power, and a sense of moral confidence.
