Colorado Republican Party

The Colorado Republican Party is the state affiliate of the Republican Party in the U.S. state of Colorado. The party's headquarters is located in Greenwood Village, Colorado. The state party chair is former state representative Dave Williams.

The Republican Party was dominant in the state as recently as the mid-2000s, however it has greatly declined over the subsequent decades. After the 2020 United States elections, Republicans held the smallest amount of political power in the state government since World War II. This decline has been attributed to various factors, including the party moving too far right for the state, changing demographics, mismanaged campaign money, internal party divisions, a better organized Democratic Party, and the unpopularity of Donald Trump in the state.

The party fared even poorer in the 2022 elections, in which Democrats swept every statewide office by a double-digit margin, expanded their dominance in the state's U.S. House delegation, and further expanded their supermajorities in both chambers of the legislature. In the aftermath of the heavily lopsided results of the 2022 elections, one Republican state representative lamented that “Colorado Republicans need to take this and learn the lesson that the party is dead. This was an extinction-level event.” Since 2023, the party has suffered a significant loss of revenue, further party infighting, the party veering further towards the right, and an overall further decline of influence in the state.
