(Minor nitpick: Arthur Coleman Winters actually identifies himself as the President-elect of the United States, not the President. While it's probably RTD making an error, I choose to interpret that line as being literally accurate. To accommodate this, I conjecture that both the U.S. and U.K. had elections in November of 2008, with President-elect Winters successfully lobbying the outgoing President Bush to get the U.N. to appoint
him as U.N. envoy to the Toclafane rather than Bush.
From Winters's assassination, I presume that his running mate, Senator John McCain, assumed the Presidency, and held office either until dying in the Dalek Invasion or until being impeached following the 4-5-6 Crisis, upon which time a young Congressman Barack Obama, who had previously gotten himself elected Speaker of the House subsequent to the Dalek Invasion, was thereby elevated to the Presidency in time for Christmas 2009 and the Master Race crisis. Just my little bit o' conjecture, that.
