Now that Barack Obama has all but sealed up the Democratic nomination, the two major competitors for the presidential race are set. A year from now, either Obama or John McCain will be president and the other will be that guy who was almost president. It's easy for the presidential losers to fall into obscurity...until now. In 5 minutes, can you name the last 10 presidential also-rans (starting with the 1968 race)? Last names will suffice, but feel free to give the candidates' full name if you know it.
