presidential election

In the 1940 presidential campaign, one song reached across party lines and had everyone cheering. It was an unlikely hit: "The Ballad for Americans," an operatic folk cantata that ran 10 minutes.

Only one person can win the presidency in 2016, and some of the 22 running have scant chance of victory. So why are they in the race? Many hope luck is on their side, but some might have other goals.
