A reader in the comments:
Consider the ratio of winners' votes to runners'-up votes in the
last 25 Presidential elections.
Obama won a clear victory with a ratio of 1.13 over McCain. (63.0 /
55.8 = 1.13)
But by any reasonable historical standard, this election was
actually fairly close.
The average over the last 25 elections has been 1.30. For the last
12 its 1.22....
