Video explains "Congressional Elections"

In this video, Craig Benzine talks about the importance of elections. But he isn’t going to focus on presidential elections, but instead those of the strongest part of our government: congressional elections. Craig will talk about the frequency of elections in the Senate and House, typical characteristics of a candidate, and the motivating factors our congresspeople follow to get re-elected.
Philippine Elections are of several types. The president, vice-president, and the senators are elected for a six-year term, while the members of the House of Representatives, governors, vice-governors, members of the Sangguniang Panlalawigan (provincial board members), mayors, vice-mayors, members of the Sangguniang Panlungsod/members of the Sangguniang Bayan (city/municipal councilors), barangay officials, and the members of the Sangguniang Kabataan (youth councilors) are elected to serve for a three-year term. https://en.wikipedia.org/wiki/Elections_in_the_Philippines

The Congress or Kongreso has two chambers. The House of Representatives or Kapulungan ng mga Kinatawan has 292 seats as of 2013, of which 80% are contested in single seat electoral districts and 20% are allotted to party-lists according to a modified Hare quota with remainders disregarded and a three-seat cap. These party list seats are only accessible to marginalized and under-represented groups and parties, local parties, and sectoral wings of major parties that represent the marginalized. The Constitution of the Philippines allows the House of Representatives to have more than 250 members by statute without a need for a constitutional amendment. The Senate or Senado has 24 members which are elected on a nationwide at-large basis; they do not represent any geographical district. Half of the Senate is renewed every three years. https://en.wikipedia.org/wiki/Elections_in_the_Philippines
