It means you have ONE election, not lots. If the various parties in the US want to hold elections to determine who will be their leaders then let them. That has got zip to do with a general election. As it is, with only two main parties in the US, you already have elections in which the person who becomes president is often the person MOST people didn't want. That can be said of GW Bush for example. He got 51% of the vote, yes. BUT, because it seems to people that they have to choose between Reps or Dems (and not WASTE their votes on better candidates who belong to parties that 'will not win so why waste the vote), the you already have a situation in which more people vote for someone who does NOT get elected. If you have 100 voters, three main people running, you could have someone elected with only 34% of the popular vote. True. So what? That's a plurality.
