United States congressional apportionment
United States congressional apportionment is the process[1] by which seats in the United States House of Representatives are distributed among the 50 states according to the most recent decennial census mandated by the United States Constitution. Each state is apportioned a number of seats which approximately corresponds to its share of the aggregate population of the 50 states.[2] However, every state is constitutionally guaranteed at least one seat.
Federal Senate
Currently, the Senate comprises 81 seats. Three Senators from each of the 26 states and three Senators from the Federal District are elected on a majority basis to serve eight-year terms. Elections are staggered so that two-thirds of the upper house is up for election at one time and the remaining one-third four years later. When one seat is up for election in each State, each voter casts one vote for the Senate; when two seats are up for election, each voter casts two votes, and the voter cannot give his two votes for the same candidate, but, in elections for the renewal of two-thirds of the Senate, each party can present two candidates for election. The candidate in each State and the Federal District (or the first two candidates, when two thirds of the seats are up for election) who achieve the greatest plurality of votes are elected.
