If there is a vacancy in the Colorado General Assembly , a vacancy committee selects a replacement. The committee consists of members of the same political party that previously held the seat, including any county commissioners from that party who live in the district.

Depending on when the vacancy occurs, the replacement must stand for election either in the next general election or in a special election. These vacancy elections are limited to voters registered with the same political party as the previous officeholder and to unaffiliated voters.

If the vacancy occurs in an even-numbered year, before July 31: The appointee is selected by the committee and runs in the regularly scheduled general election that year.

If the vacancy occurs in an even-numbered year, after July 31: The appointee is selected by the committee and must run in a special vacancy election held in November of the following odd-numbered year.

If the vacancy occurs in an odd-numbered year, before July 31: The appointee is selected by the committee and runs in a special vacancy election that same November.

If the vacancy occurs in an odd-numbered year, after July 31: The appointee is selected by the committee and runs in the next general election, which occurs in the following even-numbered year.

If the previous member was unaffiliated with a political party, then the vacancy is filled by the vacancy committee designated on their original nomination petition. If the member has no vacancy committee, the governor appoints a replacement.

Redistricting

On November 15, 2021, the Colorado Supreme Court approved the state legislative redistricting plans approved by the state's Independent Legislative Redistricting Commission on October 11 and 12, 2021.^[10] These maps took effect for Colorado’s 2022 state legislative elections.

The Colorado Sun's Thy Vo wrote that the House and Senate maps "appear to favor Democrats' maintaining their majority in the General Assembly."^[10] Colorado Politics' Evan Wyloge wrote that the new maps created nine House districts where previous election results fell within a five percentage point margin and eight such Senate districts. At the time of approval, Democrats held a 42-23 majority in the House and a 20-15 majority in the Senate.^[11]

How does redistricting in Colorado work? On November 6, 2018, Colorado voters approved two constitutional amendments, Amendment Y and Amendment Z, establishing separate non-politician commissions for congressional and state legislative redistricting. Each commission consists of four members belonging to the state's largest political party, four members belonging to the state's second-largest party, and four members belonging to no party. Commission members are appointed by a panel of three judges selected by the Chief Justice of the Colorado Supreme Court. The amendment requires at least eight of the commission's 12 members, including at least two members not belonging to any political party, to approve a map.^[12]

The Colorado Constitution requires that state legislative district boundaries "be contiguous, and that they be as compact as possible based on their total perimeter." In addition, "to the extent possible, districts must also preserve the integrity of counties, cities, towns and–where doing so does not conflict with other goals–communities of interest." There are no similar requirements for congressional districts.^[13]^[14]
