The elections you're describing in November 2024, where voters will elect all members of the House of Representatives and one-third of the Senate, including a Senate seat in Ohio, are examples of midterm elections in the United States. Midterm elections occur every four years, halfway through a president's term, and typically involve elections for the House of Representatives, a portion of the Senate, and various state and local offices.
Additionally, this situation also highlights congressional elections, which specifically pertain to the election of members of the United States Congress, comprising both the House of Representatives and the Senate. Voter participation during these elections plays a crucial role in shaping the legislative agenda and political landscape of the country.
