Burr is about the Founding Father who has been airbrushed out of history. Aaron Burr very nearly became America's third president in 1800, when he narrowly lost to Thomas Jefferson. He ended up as Jefferson's Vice-President and, four years later, while still in office, he killed Alexander Hamilton in a duel, which killed his own political career.

History has painted Burr as a chancer and a rogue. Vidal takes Burr's side to show that he was much better than that: a chancer, for sure, but self-aware enough to know that's what he was, which makes him intensely likable. In this novel, the usual pantheon of American heroes – Washington, Jefferson, Hamilton – come across as various stripes of pompous hypocrite. Burr is the one you want to win.
