Philippine Senate 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. This means they have to join coalitions or alliances in order to present a full slate. If a slate is still not complete, "guest candidates" may be invited, even from rival slates. A guest candidate may not be compelled to join the campaign rallies of the slate that invited him/her. A party may even not include their entire ticket to a coalition slate, or assign their candidates to competing slates. A candidate may defect from one slate to another or be unaffiliated with any slate while the campaign is ongoing. The Commission on Elections uses the names of the political parties on the ballot. Once elected, the parties involved in the different slates may form alliances with one another totally different from the alliances prior to the election. In Third Republic elections under the nominal two-party system, the Liberal Party and the Nacionalista Party often presented complete 8-person tickets; a party may even exceed the 8-person slate due to perceived popularity. The first instance of having guest candidates was in 1955, when the opposition Liberals adopted Claro M. Recto of the Nacionalista Party, who had also opposed the presidency of Ramon Magsaysay. Parties having guest candidates was seen as a weakness of finding candidates within their ranks. ==Manner of election==

1916 to 1935 From 1916 to 1934, the country was divided into 12 senatorial districts. Eleven of these districts elected two senators each. In 1916, each district elected two senators (plurality-at-large): one was to serve a six-year term, the other a three-year term. On each election thereafter, one seat per district was up (first past the post). The senators from the 12th district were appointed by the American governor-general for no fixed term. In 1935, the electorate approved in a plebiscite a new constitution that abolished the Senate and instituted a unicameral National Assembly of the Philippines. The members of the Constitutional Convention originally wanted bicameralism but could not agree on how the senators shall be elected: via the senatorial districts or being nationally elected. 1941 to 1949 The electorate in 1940 approved in a plebiscite amendments to the constitution that restored the bicameral Congress of the Philippines, including the Senate. Elections for the Senate were held on every second Monday of November of every odd-numbered year; however, the old senatorial districts were not used anymore; instead, the 24-member Senate was to be elected on a nationwide at-large basis. Due to World War II, Congress was not able to convene until June 1945. President Sergio Osmeña called for special sessions to convene the 1st Congress of the Commonwealth of the Philippines until elections could be organized. Originally, to observe the staggered terms, the eight candidates with the most votes were to serve for eight years, the next eight for four years, and still the next eight for two years. However, several members had died and others were disqualified because they were charged with collaboration with the Japanese, so the Senate conducted a lottery to determine which senators would serve until 1946 and which would serve until 1947. In the 1946 election, voters elected 16 senators; the first eight candidates with the highest number of votes were to serve until 1951, the next eight were to serve until 1949. Summary ==List of results==

Senatorial districts era At-large era In this table, the "administration" ticket is the ticket supported by the sitting president. In 1992, Corazon Aquino who was nominally supporting the LDP, supported the presidential candidacy of Fidel V. Ramos of Lakas, making the "administration ticket" ambiguous. In 2021, ruling party PDP–Laban nominated Senator Bong Go for president, and President Rodrigo Duterte for vice president. Later on, Senator Ronald dela Rosa filed his candidacy to run for president under PDP–Laban, while Go as his vice president. There were suggestions that Davao City Mayor Sara Duterte, the president's daughter, substitute for dela Rosa. Instead, dela Rosa withdrew his presidential candidacy, Go then withdrew his vice presidential bid to avoid complications with Sara's vice presidential candidacy under Lakas–CMD, then Go became the presidential nominee of Pederalismo ng Dugong Dakilang Samahan, with President Duterte filing to run for senator, then endorsing his daughter for vice president. In the end, both Go and President Duterte withdrew, and several figures in the Duterte administration were either senatorial candidates of the PDP–Laban backed Tuloy ang Pagbabago slate, or Mayor Duterte's UniTeam Alliance, making the "administration ticket" ambiguous. == By demographics ==

Since the at-large era, a high-scoring winner can be seen as a strong contender for a future presidential or vice-presidential bid. Pacita Madrigal-Warns is the first woman to be a senatorial topnotcher. Jovito Salonga is the first senatorial candidate to take the top spot thrice; Loren Legarda comes in second by topping the polls twice. == Senate composition ==

These are at the start of each Congress. A senator may change parties or leave office mid-term. ==Latest elections==
