Sorry to disappoint you but you're thinking like a Hillary fanboy, not an anthropologist. Democrats had better options available that'd have beaten Trump but people like you decided that Hillary was supposed to be the next president. Not many opponents would be so good at electing Trump.
I picked an example at random that I knew everyone would be familiar with. I have no skin in this game and who won or didn't win isn't the point. The point is the rules of the game.
