Voting

Voting is a method for a group, such as a meeting or an electorate, in order to make a collective decision or express an opinion, usually following discussions, debates or election campaigns. Democracies elect holders of high office by voting. Residents of a place represented by an elected official are called 'constituents', and those constituents who cast a ballot for their chosen candidate are called 'voters'. There are different systems for collecting votes.

Democracies elect holders of high office by voting. Residents of a place represented by an elected official are called 'constituents', and those constituents who cast a ballot for their chosen candidate are called 'voters'. There are different systems for collecting votes. In a democracy, a government is chosen by voting in an election: a way for an electorate to elect, i.e. choose, among several candidates for rule. In a representative democracy voting is the method by which the electorate appoints its representatives in its government.In a direct democracy, voting is the method by which the electorate directly make decisions, turn bills into laws, etc. A vote is a formal expression of an individual's choice for or against some motion (for example, a proposed resolution); for or against some ballot question; or for a certain candidate, selection of candidates, or political party. Many countries use a secret ballot, a practice to prevent voters from being intimidated and to protect their political privacy. Voting often takes place at a polling station; it is voluntary in some countries, compulsory in others, such as Australia. Different voting systems use different types of votes. Plurality voting does not require the winner to achieve a vote majority, or more than fifty percent of the total votes cast. In a voting system that uses a single vote per race, when more than two candidates run, the winner may commonly have less than fifty percent of the vote. A side effect of a single vote per race is vote splitting, which tends to elect candidates that do not support centrism, and tends to produce a two-party system. An alternative to a single-vote system is approval voting. To understand why a single vote per race tends to favor less centric candidates, consider a simple lab experiment where students in a class vote for their favorite marble. If five marbles are assigned names and are placed 'up for election', and if three of them are green, one is red, and one is blue, then a green marble will rarely win the election. The reason is that the three green marbles will split the votes of those who prefer green. In fact, in this analogy, the only way that a green marble is likely to win is if more than sixty percent of the voters prefer green. If the same percentage of people prefer green as those who prefer red and blue, that is to say if 33 percent of the voters prefer green, 33 percent prefer blue, and 33 percent prefer red, then each green marble will only get eleven percent of the vote, while the red and blue marbles will each get 33 percent, putting the green marbles at a serious disadvantage. If the experiment is repeated with other colors, the color that is in the majority will still rarely win. In other words, from a purely mathematical perspective, a single-vote system tends to favor a winner that is different from the majority. If the experiment is repeated using approval voting, where voters are encouraged to vote for as many candidates as they approve of, then the winner is much more likely to be any one of the five marbles, because people who prefer green will be able to vote for every one of the green marbles. A development on the 'single vote' system is to have two-round elections, or repeat first-past-the-post. This system is most common around the world. In most cases, the winner must receive a majority, which is more than half. and if no candidate obtains a majority at the first round, then the two candidates with the largest plurality are selected for the second round. Variants exist on these two points: the requirement for being elected at the first round is sometimes less than 50%, and the rules for participation in the runoff may vary. An alternative to the Two-round voting system is the single round instant-runoff voting system (Also referred to as Alternative vote or Preferential voting) as used in some elections in Australia, Ireland and the USA. Voters rank each candidate in order of preference (1,2,3 etc.). Votes are distributed to each candidate according to the preferences allocated. If no single candidate has 50% of the vote, then the candidate with the fewest votes is excluded and their votes redistributed according to the voters nominated order of preference. The process repeating itself until a candidate has 50% or more votes. The system is designed to produce the same result as an exhaustive ballot but using only a single round of voting.
