Which body of Congress has elected representatives for a term of two years?

The U.S. House of Representatives is characterized by its structure of having members elected to serve two-year terms. This short term allows for greater responsiveness to the changing sentiments and needs of the electorate, reflecting the democratic principle of accountability. Representatives must seek re-election more frequently, which encourages them to remain engaged with their constituents and address their concerns more directly.

In contrast, the U.S. Senate consists of elected members who serve six-year terms, promoting a more stable and longer-term perspective in governance. The term lengths of other bodies, such as state legislatures, can vary widely by state and are not consistently set at two years across the board. Joint Congress, as a term, doesn't refer to a formal legislative body with elected representatives, which further underscores the specificity of the two-year term associated with the U.S. House of Representatives.
