how many electoral districts are there in the us
Lists of electoral districts by nation In the United States, electoral constituencies for the federal House of Representatives are known as congressional districts (of which there are presently 435; the number can be changed but has remained at 435 since 1912, except for a brief period from 1959-1962 when two seats were temporarily added for the then-new States of Alaska and Hawaii), while the constituencies for the variously named state legislatures go by a variety of names (and have differing numbers). Long standing practice, reinforced and modified by several U.S. Supreme Court decisions, require the equalization of populations of constituencies after each decennial census, a process known as redistricting.
United States House of Representatives The United States House of Representatives is the lower chamber of the United States Congress. The Senate is the upper chamber. Together they compose the legislature of the United States.
United States presidential election The Electoral College and its procedure is established in the U.S. Constitution by Article II, Section 1, Clauses 2 and 4; and the Twelfth Amendment (which replaced Clause 3 after its ratification in 1804). Under Clause 2, each of the states casts as many electoral votes as the total number of its Senators and Representatives in Congress, while, per the Twenty-third Amendment ratified in 1961, Washington, D.C. casts the same number of electoral votes as the least-represented state, which is three. Also under Clause 2, the manner for choosing electors is determined by each state legislature, not directly by the federal government. Many state legislatures previously selected their electors directly, but over time all of them switched to using the popular vote to help determine electors, which persists today. Once chosen, electors generally cast their electoral votes for the candidate who won the plurality in their state, but at least 21 states do not have provisions that specifically address this behavior; those who vote in opposition to the plurality are known as "faithless" or "unpledged electors".[1] In modern times, faithless and unpledged electors have not affected the ultimate outcome of an election, so the results can generally be determined based on the state-by-state popular vote.
United States Senate The United States Senate is the upper chamber of the United States Congress, which along with the United States House of Representatives—the lower chamber—comprises the legislature of the United States.
