The Colorado Senate is the upper chamber of the Colorado General Assembly. It is comprised of 35 senators: 16 Democrats, 1 Independent, and 18 Republicans.
The Colorado General Assembly is a part-time state legislature. The 2018 legislative session — the period during which bills can be introduced and passed — takes place between Wednesday, January 10 and Wednesday, May 9.
Each Senator may introduce up to five bills per legislative session. Bills are referred to committees and scheduled for votes by the majority party. Republicans currently hold a majority in the Colorado Senate, giving them control over this process.
