Prior to this year, Obama has run in just one seriously contested election—for Congress, in 2000. He lost in a landslide. His victories, right up until his foray into the presidential primaries, have come almost effortlessly, owing largely to incredible good luck and the fact that his opponents’ faults were much greater than his own. This makes him an unknown quantity, even now as he runs for president.
