The Senate is composed of 21 members, each of whom is elected to a four-year term, except when reapportionment occurs at which time Senators may be elected to a two-year term. Democrats currently hold 12 of these seats and 9 are held by Republicans. There is no limit to the number of terms that a Senator may serve.

The Lieutenant Governor serves as the President of the Senate, but only casts a vote if required to break a tie. In his or her absence, the President Pro Tempore presides over the Senate. The President Pro Tempore is elected by the majority party caucus followed by confirmation of the entire Senate through a Senate Resolution. The President Pro Tempore is the chief leadership position in the Senate. The other Senate leaders are elected by their respective party caucuses.

Senators must be citizens of the United States, have lived in Delaware for three years and been a resident of their respective district for at least one year preceding their election and must be at least 27 years old by the time of their election
