There are 35 Senators who serve the state of Colorado. Senators are elected to four-year terms, and may serve a total of two consecutive terms. Senators must have attained the age of twenty-five years, be a United States citizen, and be a resident of the district from which the Senator is elected for at least twelve months prior to election. The Senate is divided so that one-half of the Senators are elected biennially, as nearly as practicable.

Committee Membership

There are 10 Senate committees of reference appointed at the beginning of each regular session following a general election. The majority leader determines the party representation of the committees in proportion to the relative number of members of the two major political parties in the Senate. The majority leader also determines the number of members on each committee, appoints the majority members to each committee, and designates the chair and vice-chair for each committee. The minority leader appoints minority members to the committees.
