By the way plurality means that when a candidate receive more votes than other candidates while not receiving a clear majority of votes. I think without plurality we would not have a president. Voters in presidential elections are people who want to express a political preference rather than people who think that a single vote may decide an election. You have to be 18 to vote in a election to choose your president.
