Parliament of South AustraliaThe Parliament of South Australia is the bicameral legislature of the Australian state of South Australia. It consists of the 47-seat House of Assembly (lower house) and the 22-seat Legislative Council (upper house). General elections are held every 4 years, with all of the lower house and half of the upper house filled at each election. It follows a Westminster system of parliamentary government with the executive branch required to both sit in parliament and hold the confidence of the House of Assembly.
Overhang seatOverhang seats are constituency seats won in an election under the traditional mixed member proportional (MMP) system (as it originated in Germany), when a party's share of the nationwide votes would entitle it to fewer seats than the number of individual constituencies won. The electoral reform in Germany removed the overhang seats, and replaced with Zweitstimmendeckung. Under MMP, a party is entitled to a number of seats based on its share of the total vote.
Political representationPolitical representation is the activity of making citizens "present" in public policy-making processes when political actors act in the best interest of citizens. This definition of political representation is consistent with a wide variety of views on what representing implies and what the duties of representatives are. For example, representing may imply acting on the expressed wishes of citizens, but it may alternatively imply acting according to what the representatives themselves judge is in the best interests of citizens.
Unionism in IrelandUnionism is a political tradition on the island of Ireland that favours political union with Great Britain and professes loyalty to the British Crown and constitution. As the overwhelming sentiment of Ireland's Protestant minority, following Catholic Emancipation (1829) unionism mobilised to keep Ireland part of the United Kingdom and to defeat the efforts of Irish nationalists to restore a separate Irish parliament.
Dual-member proportional representationDual-member proportional representation (DMP), also known as dual-member mixed proportional, is an electoral system designed to produce proportional election results across a region by electing two representatives in each of the region’s districts. The first seat in every district is awarded to the candidate who receives the most votes, similar to first-past-the-post voting (FPTP). The second seat is awarded to one of the remaining district candidates so that proportionality is achieved across the region, using a calculation that aims to award parties their seats in the districts where they had their strongest performances.
PlaymanderThe Playmander was a gerrymandering system, a pro-rural electoral malapportionment in the Australian state of South Australia, which was introduced by the incumbent Liberal and Country League (LCL) government in 1936, and remained in place for 32 years until 1968. This consisted of 26 low-population rural seats holding as much as a 10-to-1 advantage over the 13 high-population metropolitan seats in the state parliament, even though rural seats contained only a third of South Australia's population during this period.
Safe seatA safe seat is an electoral district (constituency) in a legislative body (e.g. Congress, Parliament, City Council) which is regarded as fully secure, for either a certain political party, or the incumbent representative personally or a combination of both. With such seats, there is very little chance of a seat changing hands because of the political leanings of the electorate in the constituency concerned and/or the popularity of the incumbent member. The opposite (i.e. more competitive) type of seat is a marginal seat.
Political polarizationPolitical polarization (spelled polarisation in British English) is the divergence of political attitudes away from the center, towards ideological extremes. Most discussions of polarization in political science consider polarization in the context of political parties and democratic systems of government. In two-party systems, political polarization usually embodies the tension of its binary political ideologies and partisan identities.
Voting blocA voting bloc is a group of voters that are strongly motivated by a specific common concern or group of concerns to the point that such specific concerns tend to dominate their voting patterns, causing them to vote together in elections. For example, Beliefnet identifies 12 main religious blocs in American politics, such as the "Religious Right", whose concerns are dominated by religious and sociocultural issues; and American Jews, who are identified as a "strong Democratic group" with liberal views on economics and social issues.
IncumbentThe incumbent is the current holder of an office or position, usually in relation to an election. In an election for president, the incumbent is the person holding or acting in the office of president before the election, whether seeking re-election or not. In some situations, there may not be an incumbent at time of an election for that office or position (ex; when a new electoral division is created), in which case the office or position is regarded as vacant or open.
