Congressional elections are held every ____ years.

Congressional elections are held every two years, which aligns with the structure and timelines set by the United States Constitution. This frequency applies to all members of the House of Representatives, as they serve two-year terms and are thus up for election every cycle. In contrast, Senators serve six-year terms, with one-third of the Senate elected every two years. Therefore, regular elections for congressional representatives occur biennially, ensuring that the House is continuously responsive to the electorate's changing sentiments and needs. This system reflects the Founding Fathers' intent to make the legislative body accountable to the public through frequent elections.
