Proportional representation (PR) refers to any type of electoral system under which subgroups of an electorate are reflected proportionately in the elected body. The concept applies mainly to political divisions among voters. The essence of such systems is that all votes cast – or almost all votes cast – contribute to the result and are effectively used to help elect someone – not just a bare plurality or (exclusively) the majority – and that the system produces mixed, balanced representation reflecting how votes are cast.
The two-round system (TRS), also known as runoff voting, second ballot, or ballotage, is a voting method used to elect a single candidate. The first round is held using simple plurality to choose the top-two candidates, and then in the second round the winner is chosen by majority vote. The two-round system is widely used in the election of legislative bodies and directly elected presidents.
Strategic or tactical voting is voting in consideration of possible ballots cast by other voters in order to maximize one's satisfaction with the election's results. For example, in plurality or instant-runoff, a voter may recognize their favorite candidate is unlikely to win and so instead support a candidate they think is more likely to win.
Single non-transferable vote or SNTV is an electoral system used to elect multiple winners. It is a generalization of first-past-the-post, applied to multi-member districts with each voter casting just one vote. Unlike FPTP, which is a single-winner system, in SNTV multiple winners are elected, typically in electoral districts; additionally, unlike FPTP, SNTV produces mixed representation and makes it unlikely for a single party to take all the seats in a city or a set area, which can happen under FPTP.
Primary elections, or direct primary, are voting processes by which voters can indicate their preference for their party's candidate, or a candidate in general, in an upcoming general election, local election, or by-election. Depending on the country and administrative divisions within the country, voters might consist of the general public in what is called an open primary, or solely the members of a political party in what is called a closed primary. In addition to these, there are other variants on primaries that are used by many countries holding elections throughout the world.
Block voting, also known as bloc voting, refers to certain electoral systems where multiple candidates are elected simultaneously. They do not guarantee minority representation and allow a group of voters to ensure that only their preferred candidates are elected. In these systems, a voter can select as many candidates as there are open seats. That is, the voter has as many votes to cast as the number of seats to fill. The block voting systems are among various election systems available for use in multi-member districts where the voting system allows for the selection of multiple winners at once.
The American Independent Party (AIP) is a political party in the United States founded in 1968.
The electoral system of Australia comprises the laws and processes used for the election of members of the Australian Parliament and is governed primarily by the Commonwealth Electoral Act 1918. The system presently has a number of distinctive features including compulsory enrolment; compulsory voting; majority-preferential instant-runoff voting in single-member seats to elect the lower house, the House of Representatives; and the use of the single transferable vote proportional representation system to elect the upper house, the Senate.
Ballot access are rules and procedures regulating the right to candidacy, the conditions under which a candidate, political party, or ballot measure is entitled to appear on voters' ballots in elections in the United States. The jurisprudence of the right to candidacy and right to create a political party are less clear than voting rights in the United States. However, the U.S. Supreme Court has established in multiple cases that the federal constitution does not recognize a fundamental right to candidacy, and that state governments have a legitimate government interest in blocking "frivolous or fraudulent candidacies". As election processes are decentralized by Article I, Section 4, of the United States Constitution, ballot access laws are established and enforced by the states. As a result, ballot access processes may vary from one state to another. State access requirements for candidates generally pertain to personal qualities of a candidate, such as: minimum age, residency, and citizenship. Additionally, many states require prospective candidates to collect a specified number of qualified voters' signatures on petitions of support and mandate the payment of filing fees before granting access; ballot measures are similarly regulated. Each state also regulates how political parties qualify for automatic ballot access, and how those minor parties that do not can. Fundamental to democracy, topics related to ballot access are the subject of considerable debate in the United States.
An electoral swing analysis shows the extent of change in voter support, typically from one election to another, expressed as a positive or negative percentage. A multi-party swing is an indicator of a change in the electorate's preference between candidates or parties, often between major parties in a two-party system. A swing can be calculated for the electorate as a whole, for a given electoral district or for a particular demographic.
In electoral systems which use ranked voting, a donkey vote is a cast ballot where the voter ranks the candidates based on the order they appear on the ballot itself. The voter that votes in this manner is referred to as a donkey voter.
The 1792–93 United States House of Representatives elections were held on various dates in various states between August 27, 1792, and September 6, 1793. Each state set its own date for its elections to the House of Representatives before the first session of the 3rd United States Congress convened on December 2, 1793. With the addition of the new state of Kentucky's representatives, and the congressional reapportionment based on the 1790 United States census, the size of the House increased to 105 seats.
In American politics, straight-ticket voting or straight-party voting refers to the practice of voting for every candidate that a political party has on a general election ballot. In some states, ballots may offer a straight-ticket voting option, sometimes known as a master lever, that allows voters to check a box and vote for all of a party's candidates, instead of voting for each race individually.
In primary elections in the United States, crossover voting refers to a behavior in which voters cast ballots for a party with which they are not traditionally affiliated. Even in the instance of closed primary elections, in which voters are required to receive a ballot matching their own political party, crossover voting may still take place, but requires the additional step of voters to change their political affiliation ahead of the primary election.
In Australia, how-to-vote cards (HTV) are small leaflets that are handed out by party supporters during elections. Voting in the Australian lower house uses a preferential voting system. Voters must rank every candidate on the ballot in order for their vote to count. There are often numerous candidates on the ballot, some with little public profile, so voters may find it difficult to decide on all of them. Parties produce how-to-vote cards ostensibly to help voters. They contain details about the candidate or party as well as instruction how to cast a ranked vote in the order that the party would prefer the voter follow. The flow of preferences can assist the party dispersing the cards directly and indirectly help allied parties.
The election of the president and the vice president of the United States is an indirect election in which citizens of the United States who are registered to vote in one of the fifty U.S. states or in Washington, D.C., cast ballots not directly for those offices, but instead for members of the Electoral College. These electors then cast direct votes, known as electoral votes, for president, and for vice president. The candidate who receives an absolute majority of electoral votes is then elected to that office. If no candidate receives an absolute majority of the votes for president, the House of Representatives elects the president; likewise if no one receives an absolute majority of the votes for vice president, then the Senate elects the vice president.
The 1957 Philadelphia municipal election, held on November 5, involved the election of the district attorney, city controller, and the remainder of a term for one city council seat, as well as several row offices and judgeships. Democrats were successful citywide, continuing a run of victories racked up after the passage of a new city charter in 1951 despite growing divisions between factions of the party. Victor H. Blanc, the incumbent district attorney, led the Democratic ticket to victory. They held the city council seat and took two citywide offices that Republicans had won in 1953. In the judges' elections, most were endorsed by both parties but in the one race that pitted a Democratic candidate against a Republican, the Democrats were successful in seating their candidate, former Congressman Earl Chudoff.
The 1948 United States presidential election in Florida was held on November 2, 1948. Voters chose eight electors, or representatives to the Electoral College, who voted for president and vice president.
In the 1856 Chicago mayoral election, Thomas Dyer defeated former mayor Francis Cornwall Sherman. The race was shaped by the divisive national political debate surrounding the issue of slavery, particularly debate surrounding the controversial Kansas–Nebraska Act, and the election was treated by many as a referendum on it. Dyer vocally supported the act, while Sherman stood in opposition to it.
