Philippine Senate electionsElections to the Senate of the Philippines are done via plurality-at-large voting; a voter can vote for up to twelve candidates, with the twelve candidates with the highest number of votes being elected. The 24-member Senate uses staggered elections, with only one-half of its members up for election at any given time, except for special elections, which are always held concurrently with regularly scheduled elections. With the advent of the nominal multi-party system In 1987, political parties have not been able to muster enough candidates to fill their 12-person slate.
Limited votingLimited voting (also known as partial block voting) is a voting system in which electors have fewer votes than there are positions available. The positions are awarded to the candidates who receive the most votes absolutely. In the special case in which the voter may vote for only one candidate and there are two or more posts, this system is called the single non-transferable vote or sometimes the strictly limited vote. The town of Voterville elects three representatives to the local legislature.
Multiple non-transferable voteThe multiple non-transferable vote (MNTV) is a group of voting system, in which voters elect several representatives at once, with each voter having more than one vote. MNTV uses multi-member electoral districts or only one district, which contains all voters, which is used to provide at-large representation. MNTV systems are not designed towards obtaining proportional representation; instead the usual result is that where the candidates divide into definitive parties (especially for example where those parties have party lines which are whipped) the most popular party in the district sees its full slate of candidates elected, resulting in a landslide.
Electoral systemAn electoral system or voting system is a set of rules that determine how elections and referendums are conducted and how their results are determined. Electoral systems are used in politics to elect governments, while non-political elections may take place in business, non-profit organisations and informal organisations. These rules govern all aspects of the voting process: when elections occur, who is allowed to vote, who can stand as a candidate, how ballots are marked and cast, how the ballots are counted, how votes translate into the election outcome, limits on campaign spending, and other factors that can affect the result.
Geographical constituencyIn Hong Kong, geographical constituencies, as opposed to functional constituencies, are elected by all eligible voters according to geographically demarcated constituencies. There are currently 5 geographical constituencies in Hong Kong, returning 35 members to the Legislative Council. Following the 2021 electoral reforms passed by the Standing Committee of the mainland National People's Congress, the number of members returned by geographical constituencies would be lowered to 20, while the total number of seats in the Legislative Council would be increased to 90.
At-largeAt large (before a noun: at-large) is a description for members of a governing body who are elected or appointed to represent a whole membership or population (notably a city, county, state, province, nation, club or association), rather than a subset. In multi-hierarchical bodies, the term rarely extends to a tier beneath the highest division. A contrast is implied, with certain electoral districts or narrower divisions. It can be given to the associated territory, if any, to denote its undivided nature, in a specific context.
Single non-transferable voteSingle 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.
Bullet votingBullet voting, also known as single-shot voting and plump voting, is a voting tactic, usually in multiple-winner elections, where a voter is entitled to vote for more than one candidate, but instead votes for only one candidate. A voter might do this because it is easier than evaluating all the candidates or as a form of tactical voting. Voters can use this tactic to maximize the chance that their favorite candidate will be elected while increasing the risk that other favored candidates will lose.
Duverger's lawIn political science, Duverger's law holds that single-ballot majoritarian elections with single-member districts (such as first past the post) tend to favor a two-party system. The theory is attributed to Maurice Duverger, a French sociologist who published several papers on it in the 1950s and 1960s. In the course of further research, other political scientists began calling the effect a "law" or principle. As a corollary to the law, Duverger also asserted that proportional representation favors multi-partyism, as does the plurality system with runoff elections.
General ticketThe general ticket, also known as party block voting (PBV) or ticket voting, is a type of block voting in which voters opt for a party, or a team's set list of candidates, and the highest-polling party/team becomes the winner. Unless specifically altered, this electoral system (at-large voting) results in the victorious political party receiving 100% of the seats. Rarely used today, the general ticket is usually applied in more than one multi-member district, which theoretically allows regionally strong minority parties to win some seats, but the strongest party nationally still typically wins with a landslide.
