"Courage is not a quality one normally associates with mathematicians. Yet it should apply to people who work in their attics in secret for seven years without cease on a problem that has eluded the greatest mathematical minds since first proposed in 1637."

What made Obama unique was that he was the ultimate charismatic politician - the most unknown stranger ever to achieve the presidency in the United States. No one knew who he was, he came out of nowhere, he had this incredible persona that floated him above the fray, destroyed Hillary, took over the Democratic Party and became president. This is truly unprecedented: A young unknown with no history, no paper trail, no well-known associates, self-created.
