The 100 seats in the United States Senate are divided into three classes for the purpose of determining which seats will be up for election in any two-year cycle, with only one class being up for election at a time. With senators being elected to fixed terms of six years, the classes allow about a third of the seats to be up for election in any presidential or midterm election year instead of having all 100 be up for election at the same time every six years. The seats are also divided in such a way that any given state's two senators are in different classes so that each seat's term ends in different years. Class 1 and class 2 consist of 33 seats each, while class 3 consists of 34 seats. Elections for class 1 seats are scheduled to take place in 2024, class 2 in 2026, and the elections for class 3 seats in 2028.

<span class="mw-page-title-main">Dean of the United States House of Representatives</span> Longest continuously serving member of the House of Representatives alive

The dean of the United States House of Representatives is the longest continuously serving member of the House. The current dean is Hal Rogers, a Republican from Kentucky, who has served in the House since 1981. The dean is a symbolic post whose only customary duty is to swear in a speaker of the House after they are elected. This responsibility was first recorded in 1819 but has not been observed continuously – at times, the speaker-elect was the current dean or the speaker-elect preferred to be sworn in by a member of their own party when the dean belonged to another party. The dean comes forward on the House Floor to administer the oath to the speaker-elect, before the new speaker then administers the oath to the other members.

<span class="mw-page-title-main">Indiana Senate</span> Upper house of the Indiana General Assembly

The Indiana Senate is the upper house of the Indiana General Assembly, the state legislature of the U.S. state of Indiana. The Senate is composed of 50 members representing an equal number of constituent districts. Senators serve four-year terms without term limits. According to the 2010 U.S. census, the average state senator represents 129,676 people.

United States senators are conventionally ranked by the length of their tenure in the Senate. The senator in each U.S. state with the longer time in office is known as the senior senator; the other is the junior senator. This convention has no official standing, though seniority confers several benefits, including preference in the choice of committee assignments and physical offices. When senators have been in office for the same length of time, a number of tiebreakers, including previous offices held, are used to determine seniority. Per traditions, the longest serving senator of the majority party is named president pro tempore of the Senate, the second-highest office in the Senate and the third in the line of succession to the presidency of the United States.
