Title: Rowe v Electoral Commissioner
Content:  The Constitution is silent as to many aspects of the democratic process, leaving these details to be provided by Parliament. The Constitution does however require that the members of Parliament be "directly chosen by the people". For members of the Senate section 7 of the Constitution provides :"The Senate shall be composed of senators for each State, directly chosen by the people of the State, voting, until the Parliament otherwise provides, as one electorate." Similarly for members of the House of Representatives section 24 of the Constitution provides:"The House of Representatives shall be composed of members directly chosen by the people of the Commonwealth, and the number of such members shall be, as nearly as practicable, twice the number of the senators." The High Court had previously held in 
Title: Election law
Content:  Elections in the United States are held for government officials at the federal, state, and local levels. At the federal level, the nation's head of state, the president, is elected indirectly by the people of each state, through an Electoral College. Today, these electors almost always vote with the popular vote of their state. All members of the federal legislature, the Congress, are directly elected by the people of each state. There are many elected offices at state level, each state having at least an elective governor and legislature. There are also elected offices at the local level, in counties, cities, towns, townships, boroughs, and villages; as well as for special districts and school districts which may transcend county and municipal boundaries.

Title: Politics of the United States
Content:  As in the United Kingdom and in other similar parliamentary systems, in the U.S. eligible Americans vote for a specific candidate. With a federal government, officials are elected at the federal (national), state and local levels. On a national level, the president is elected indirectly by the people, but instead elected through the Electoral College. In modern times, the electors almost always vote with the popular vote of their state, however in rare occurrences they may vote against the popular vote of their state, becoming what is known as a faithless elector. All members of Congress, and the offices at the state and local levels are directly elected. Both federal and state laws regulate elections. The United States Constitution defines (to a basic extent) how federal elections are held, in Article One and Article Two and various amendments. State law regulates most aspects of electoral law, including primaries, the eligibility of voters (beyond the basic constitutional definition), the running of each state's electoral college, and the running of state and local elections.
Title: Article Two of the United States Constitution
Content:  "Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress: but no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector." Under the U.S. Constitution the president and vice president are chosen by electors, under a constitutional grant of authority delegated to the legislatures of the several states. The Constitution reserves the choice of the precise manner for selecting electors to the will of the 
Title: Republic
Content:  States president as resulting from the signing of the Constitution by nine states. The idea that direct election is required for legitimacy also contradicts the spirit of the Great Compromise, whose actual result was manifest in the clause that provides voters in smaller states with more representation in presidential selection than those in large states; for example citizens of Wyoming in 2016 had 3.6 times as much electoral vote representation as citizens of California. In states with a parliamentary system the president is usually elected by the parliament. This indirect election subordinates the president to the parliament, and also gives the president limited legitimacy and turns most presidential powers into reserve powers that can only be exercised under rare circumstance. There are exceptions where elected presidents have only ceremonial powers, such as in Ireland.
Title: President (government title)
Content:  directly elected by popular vote or indirectly elected by an electoral college or some other democratically elected body. In the United States, the president is indirectly elected by the Electoral College made up of electors chosen by voters in the presidential election. In most states of the United States, each elector is committed to voting for a specified candidate determined by the popular vote in each state, so that the people, in voting for each elector, are in effect voting for the candidate. However, for various reasons the numbers of electors in favour of each candidate are unlikely to be proportional to the 
Title: Republic
Content:  In liberal democracies, presidents are elected, either directly by the people or indirectly by a parliament or council. Typically in presidential and semi-presidential systems the president is directly elected by the people, or is indirectly elected as done in the United States. In that country the president is officially elected by an electoral college, chosen by the States, all of which do so by direct election of the electors. The indirect election of the president through the electoral college conforms to the concept of republic as one with a system of indirect election. In the opinion of some, direct election confers legitimacy upon the president and gives the office much of its political power. However, this concept of legitimacy differs from that expressed in the United States Constitution which established the legitimacy of the 
Title: Direct election
Content:  Direct election is a system of choosing political officeholders in which the voters directly cast ballots for the persons or political party that they desire to see elected. The method by which the winner or winners of a direct election are chosen depends upon the electoral system used. The most commonly used systems are the plurality system and the two-round system for single-winner elections, such as a presidential election, and party-list proportional representation for the election of a legislature. Examples of directly elected bodies are the European Parliament (since 1979) and the United States House of Representatives. The MPs (members of parliament), MLAs (members of the legislature), and members of the local bodies are elected by direct election. By contrast, in an indirect election, the voters elect a body which in turn elects the officeholder in question. In a double direct election, the elected representative serves on two councils, typically a lower-tier municipality and an upper-tier regional district or municipality.
Title: Contingent election
Content:  In the United States, the president and vice president are indirectly elected by the Electoral College, which, since ratification of the 23rd Amendment in 1961, consists of presidential electors from the 50 states and the District of Columbia. The current total of 538 electors that make up the Electoral College are directly elected by their respective states. Since the election of 1824, a majority of the states have chosen their electors on a statewide winner-take-all basis, based on the statewide popular vote on Election Day. Maine and Nebraska are the only two current exceptions, as both states use the congressional district method. Although ballots list the names of the presidential and vice presidential candidates (who run on a ticket), voters actually choose electors when they vote for president
