About

About the Colorado Elections DatabaseIn 2021, the Colorado Secretary of State created this database in order to provide an easy way for the general public to access, explore, and analyze the entire electoral history of the State of Colorado. Our mission is to consolidate into one searchable platform every candidate contest and ballot question that has been reported to the Secretary of State since 1902. This requires a process of ongoing data inventory and extraction among official sources, mostly the Abstract of Votes Cast. As we look at documents further back in time, the record becomes less comprehensive. For this reason, we have created an inventory table below to help visitors understand which contests are available as of today. The “Notes” column provides some additional detail about what data limitations one may find.InventoryOffice TypeOfficeYears AvailableNotesFederalPresidentU.S. SenateU.S. House
