However, in terms of voting and elections, majority is defined as "a number of voters or votes, jurors, or others in agreement, constituting more than half of the total number.". B, Glass 2, As is used in paragraph 2, which is the best antonym for honed? However, under Instant-Runoff Voting, Candidate B is eliminated in the first round, and Candidate C gains 125 more votes than Candidate A. \hline This system is sometimes referred to as first-past-the-post or winner-take-all. Let x denote a discrete random variable with possible values x1 xn , and P(x) denote the probability mass function of x. plural pluralities 1 : the state of being plural or numerous 2 a : the greater number or part a plurality of the nations want peace b : the number of votes by which one candidate wins over another c Middlesex Community College, 591 Springs Rd, Bedford, MA 01730. Staff Tools| Contact Us| Privacy Policy| Terms | Disclosures. After transferring votes, we find that Carter will win this election with 51 votes to Adams 49 votes! M: 15+9+5=29. The vetting is less clear - In the U.S., we have very few requirements for what a person must do to run for office and be on a ballot. \hline 3^{\text {rd }} \text { choice } & \mathrm{D} & \mathrm{B} & \mathrm{C} & \mathrm{E} & \mathrm{C} & \mathrm{B} \\ If one of the candidates has more than 50% of the votes, that candidate wins. The 44 voters who listed M as the second choice go to McCarthy. So it may be complicated to, If you look over the list of pros above you can see why towns that use IRV tend to have better voter turnout than before they started the IRV. Expert Answer. It is new - A certain percentage of people dont like change. McCarthy (M) now has a majority, and is declared the winner. For the Shannon entropy, this point is at approximately 0.6931, meaning that elections with Shannon entropy lower than 0.6931 are guaranteed to be concordant. For example, consider the algorithm for Instant-Runoff Voting shown in Table 2, and the series of ballots shown in Table 3. The winner held a majority over Santos but his share of . In Figures 1 - 5, we present the results of one million simulated elections, illustrating the probability of winner concordance on the basis of ballot concentration and entropy. If you look over the list of pros above you can see why towns that use IRV tend to have better voter turnout than before they started the IRV. Legal. RCV usually takes the form of "instant runoff voting" (IRV). A majority would be 11 votes. After clustering mock elections on the basis of their Shannon entropy and HHI, we examine how the concentration of votes relates to the concordance or discordance of election winners between the algorithms, i.e., the likelihood that the two algorithms might have produced identical winners. { "2.01:_Introduction" : "property get [Map

\hline 2^{\text {nd }} \text { choice } & \text { D } & \text { B } & \text { D } & \text { B } & \text { B } \\ Minimizes strategic voting - Instead of feeling compelled to vote for the lesser of two evils, as in plurality voting, voters can honestly vote forwho they believe is the best candidate.\. \hline 2^{\text {nd }} \text { choice } & \mathrm{C} & \mathrm{D} & \mathrm{D} & \mathrm{C} & \mathrm{C} & \mathrm{B} \\ But another form of election, plurality voting,. The 20 voters who did not list a second choice do not get transferred. The first is the ballot value and incorporates information across all ballot types. - We dont want spoilt ballots! There is still no choice with a majority, so we eliminate again. Consider the preference schedule below, in which a companys advertising team is voting on five different advertising slogans, called A, B, C, D, and E here for simplicity. The relationship between ballot concentration and winner concordance can be observed even in the absence of full voter preference information. Find the winner using IRV. At this time, based on statewide votes, legal decisions and the provisions of the Maine Constitution, the State of Maine is using ranked-choice voting for all of Maine's state-level primary elections, and in general elections ONLY for federal offices, including the office of U . The ballots and the counting of the ballots will be more expensive - It either requires a computer system, or is labor intensive to count by hand, with risk of errors. We then shift everyones choices up to fill the gaps. If no candidate has a majority of first preferences, the least popular candidate is eliminated and their votes. This is known as the spoiler problem. Notice that, in this example, the voters who ranked Montroll first had a variety of second choice candidates. In the most notable cases, such as elections for president or governor, there can only be a single winner. \hline & 5 & 4 & 4 & 6 & 1 \\ We see that there is a 50% likelihood of concordance when the winner has about one-third of the total vote, and the likelihood increases until eventually reaching 100% after the plurality winner obtains 50% of the vote. This is similar to the idea of holding runoff elections, but since every voters order of preference is recorded on the ballot, the runoff can be computed without requiring a second costly election. W: 37+9=46. Under this algorithm, voters express not only a first choice as in the Plurality algorithm, but an ordered list of preferred candidates (Table 1) which may factor into the determination of a winner. \hline 1^{\text {st }} \text { choice } & \mathrm{G} & \mathrm{G} & \mathrm{G} & \mathrm{M} & \mathrm{M} & \mathrm{B} & \mathrm{B} \\ Choice E has the fewest first-place votes, so we remove that choice, shifting everyones options to fill the gaps.
