The American population is about 320 - 325 million including illegal immigrants.
Obama got 63 million votes and McCain 56 million.
That means 1 in 6 Americans voted for Obama. nearly 1 in 6 voted for McCain.
If that is 'unity' then they must have some odd idea of what 'unity' is.
If that is democratic mandate - around 18 % of the US population - then that is some strange democracy.
I thought a democracy was the will of the majority - not the Tyranny Of The Minority.
