Who did more damage to the history of this country, John Wilkes Booth or Lee Harvey Oswald?

With a single act, both changed the results of an election, and the course of history. Feel free to nominate other candidates.
Update: Memo to Neville: "Good question," but no star. Pourquoi pas?
Update 2: You are all wrong IMO. LBJ followed JFK, and comitted us to the Vietnam War, which practically destroyed the fabric of this Country. Not to mention, it led to the election of Richard Nixon, and economic collapse. That's the way I see things.
