Because history repeats itself, except for all the times it doesn’t.
Barack Obama’s re-election this week meant that three successive US Presidents (Bill Clinton, George W Bush and Obama) had all been elected to two terms in office. The only other time this has happened in American politics was 200 years ago, with the Presidencies of Thomas Jefferson, James Madison and James Monroe.
The interesting thing about this is that in both of these sequences, the President who served immediately beforehand was a holder of the office for a single term (John Adams and George HW Bush), who’d previously been Vice-President for two terms (for George Washington and Ronald Reagan). In the Jefferson-Madison-Monroe sequence, the next President was a son of that former President who served for a single term: John Quincy Adams.
As perfect symmetry can’t be achieved unless someone finds a way for George W Bush to run again for the Presidency, the burden of history falls on the other politically-active son of George W Bush, former Florida Governor Jeb Bush. To keep up with history, he should win a bitterly disputed election that ends up decided by the Congress, after the ruling party has split several ways. The winner of the popular vote and the most electoral votes (Andrew Jackson in 1824) will then swear revenge, get elected for two terms immediately afterwards and make radical changes to the way the political system of the country works.
Of course, the parallels break down when you look too closely, not least in how James Monroe’s period as President was known as ‘the era of good feelings’ with so little domestic strife that he was re-elected without serious opposition to his second term. When the historians write about this period of US history, I somehow doubt ‘good feelings’ will be used much. However, Jeb Bush is being mentioned as a potential Republican candidate next time round, so maybe history is preparing for the tragedy or the farce.
