Members of the Senate are called senators. Each of the 50 states is given two Senate seats. Washington D.C. and territories, such as Puerto Rico and Guam, do not receive any delegates to the Senate.
Each senator serves for a six-year term. There are no term limits for senators.[9]
According to the U.S. Constitution, senators must meet the following requirements:[10]
Additionally, all 50 states maintain requirements related to running for election. These filing requirements vary and can include:
“ | Section. 3 Clause 1: The Senate of the United States shall be composed of two Senators from each State, chosen by the Legislature thereof, for six Years; and each Senator shall have one Vote. Clause 2: Immediately after they shall be assembled in Consequence of the first Election, they shall be divided as equally as may be into three Classes. The Seats of the Senators of the first Class shall be vacated at the Expiration of the second Year, of the second Class at the Expiration of the fourth Year, and of the third Class at the Expiration of the sixth Year, so that one third may be chosen every second Year; and if Vacancies happen by Resignation, or otherwise, during the Recess of the Legislature of any State, the Executive thereof may make temporary Appointments until the next Meeting of the Legislature, which shall then fill such Vacancies. Clause 3: No Person shall be a Senator who shall not have attained to the Age of thirty Years, and been nine Years a Citizen of the United States, and who shall not, when elected, be an Inhabitant of that State for which he shall be chosen. Clause 4: The Vice President of the United States shall be President of the Senate, but shall have no Vote, unless they be equally divided. Clause 5: The Senate shall chuse their other Officers, and also a President pro tempore, in the Absence of the Vice President, or when he shall exercise the Office of President of the United States. Clause 6: The Senate shall have the sole Power to try all Impeachments. When sitting for that Purpose, they shall be on Oath or Affirmation. When the President of the United States is tried, the Chief Justice shall preside: And no Person shall be convicted without the Concurrence of two thirds of the Members present. Clause 7: Judgment in Cases of Impeachment shall not extend further than to removal from Office, and disqualification to hold and enjoy any Office of honor, Trust or Profit under the United States: but the Party convicted shall nevertheless be liable and subject to Indictment, Trial, Judgment and Punishment, according to Law.[11] |

There are 20 main committees and 68 subcommittees in the U.S. Senate. There are also several joint committees with the U.S. House of Representative. In general, the committees have legislative jurisdiction, with specific topics dealt out to the subcommittees. The majority party chairs and receives the most seats on committees. However, senators are limited to the number of committees they may take part in.
Legislation goes through committees before it reaches the full Senate for debate and approval.[12]
Every two years, 33 or 34 seats in the U.S. Senate are up for election. Seats in the U.S. Senate for the purposes of determining the year of an election are defined as Class I, Class II, and Class III. Elections for these seats take place in this rotation:

Heading into the election, the Republican Party held a 51 seat majority in the chamber. Democrats held 47 seats, and the remaining two were held by independents who caucus with the Democratic Party. The Democratic Party faced greater partisan risk in 2018, as they were defending 25 seats (two of which were held by independents), while eight seats up for election in 2018 were held by Republican incumbents by comparison. The Democratic Party had to defend seats in 10 states that supported Donald Trump (R) over Hillary Clinton (D) in 2016.

The term wave election is frequently used to describe an election cycle in which one party makes significant electoral gains. How many seats would Republicans have had to lose for the 2018 midterm election to be considered a wave election?
Ballotpedia examined the results of the 50 election cycles that occurred between 1918 and 2016—spanning from President Woodrow Wilson's (D) second midterm in 1918 to Donald Trump's (R) first presidential election in 2016. We define wave elections as the 20 percent of elections in that period resulting in the greatest seat swings against the president's party.
Applying this definition to four different election groups (U.S. Senate, U.S. House, governorships, and state legislatures) yields specific numbers of seats that Republicans needed to lose for 2018 to qualify as a wave election. Those are:
The midterm election results in 2018 met those levels in one category, as Democrats gained seven governorships. In congressional elections, Democrats had a net gain of 40 U.S. House seats while Republicans actually gained a net total of two U.S. Senate seats. Democrats gained a net 309 state legislative seats.
