Some jurisdictions that hold runoff elections allow absentee (only) voters to submit IRV ballots, because the interval between votes is too short for a second round of absentee voting. In runoff voting voters do not rank candidates in order of preference on a single ballot. Imagine that Tennessee is having an election on the location of its capital. A candidate who receives an absolute majority (50 per cent plus 1) of valid first preference votes is declared elected. [37], (The declaration by the returning officer is simply to optimize the counting process. Ballots are initially counted for each voter's top choice. Partial results exist for other models of voter behavior in the two-round method: see the two-round system article's criterion compliance section for more information. In these scenarios, it would have been better for the third party voters if their candidate had not run at all (spoiler effect), or if they had voted dishonestly, ranking their favorite second rather than first (favorite betrayal. Also, if 17% of voters in Memphis were to stay away from voting, the winner would be Nashville. The process repeats until one candidate achieves a majority of votes cast for continuing candidates. [105] Because holding many rounds of voting on separate days is generally expensive, the exhaustive ballot is not used for large-scale, public elections. The Alternative Vote is a preferential plurality/majority system used in single-member districts. In Australian elections the allocation of preferences is performed efficiently in an unofficial tally at the polling booth by having the returning officer pre-declare the two most likely winners.

[91] In litigation following the results of the 2018 election for Maine's 2nd congressional district, Representative Bruce Poliquin claimed that IRV allowed his opponents to "cast ballots for three different candidates in the same election". When the single transferable vote (STV) method is applied to a single-winner election, it becomes IRV; the government of Ireland has called IRV "proportional representation" based on the fact that the same ballot form is used to elect its president by IRV and parliamentary seats by STV, but IRV is a winner-take-all election method. Many of the mathematical criteria by which voting methods are compared were formulated for voters with ordinal preferences. [97], A 2015 study of four local U.S. elections that used IRV found that inactive ballots occurred often enough in each of them that the winner of each election did not receive a majority of votes cast in the first round. Furthermore, the United Kingdom … Pierce County, Washington, election officials outlined one-time costs of $857,000 to implement IRV for its elections in 2008, covering software and equipment, voter education and testing. [5][6][7][8][9]) is a type of ranked preferential voting counting method used in single-seat elections with more than two candidates. This is not possible in IRV, as participants vote only once, and this prohibits certain forms of tactical voting that can be prevalent in 'standard' runoff voting. Most often this is when two or more politically similar candidates divide the vote for the more popular end of the political spectrum. [54] James Green-Armytage tested four ranked-choice methods, and found the alternative vote to be the second-most-resistant to tactical voting, though it was beaten by a class of AV-Condorcet hybrids, and did not resist strategic withdrawal by candidates well.[55]. The third round of tabulation yields the following result: Result: Knoxville, which was running third in the first tabulation, has moved up from behind to take first place in the third and final round. Some critics of IRV misunderstand the tally to believe that some voters get more votes than other voters. There are five voters, "a" through "e". As an example Australia the 1972 federal election had the highest proportion of winners who would not have won under first past the post - with only 14 out of 125 seats not won by the plurality candidate.[110]. This is shown in the example Australian ballot above. [40] In its first use of IRV in 2009, Minneapolis, Minnesota, tallied first choices on optical scan equipment at the polls and then used a central hand-count for the IRV tally, but has since administered elections without hand tallies[41] Portland, Maine in 2011 used its usual voting machines to tally first choice at the polls, then a central scan with different equipment if an IRV tally was necessary.[42]. Here's a rundown on how electoral colleges work in those countries, according to … Round 2 – In the second round of tabulation, we remove the city with the least first-place support from consideration. The monotonicity criterion states that "a voter can't harm a candidate's chances of winning by voting that candidate higher, or help a candidate by voting that candidate lower, while keeping the relative order of all the other candidates equal."
