2022 Colorado Senate election
The 2022 Colorado Senate elections took place on November 8, 2022, with the primary elections held on June 28, 2022. Voters in 17 out of the 35 districts of the Colorado Senate elected their representative for a four-year term. It coincided with other Colorado elections of the same year and the biennial United States elections. Democrats gained 2 seats increasing their majority to 23 out of 35 seats, one seat shy of an outright supermajority. Background
In the previous state Senate election (2020), the Democrats increased their majority to 5 seats. In August 2022, Republican Sen. Kevin Priola announced he was changing his party affiliation to Democratic. Therefore, for Democrats to lose their absolute majority in the Senate in this election, Republicans and other parties would need to gain at least 4 more seats. This will be the first election with the districts drawn based on the 2020 census. Due to this, some districts do not have incumbents, as they chose to run in other districts that are not up for election in 2022. Incumbents not seeking re-election 
One Democratic and four Republican incumbents are term-limited and prohibited from seeking a consecutive third term. Under the laws for the state Senate, for terms to be considered non-consecutive, there needs to be a gap of at least 4 years between them. Democrats 
 District 5: Kerry Donovan was term-limited. District 11: Pete Lee retired. District 16: Tammy Story retired to run for state representative from District 25. District 22: Brittany Pettersen retired to run for U. S. representative from Colorado's 7th congressional district. Republicans 
 District 1: Jerry Sonnenberg was term-limited. District 6: Don Coram retired to run for U. S. representative from Colorado's 3rd congressional district. District 7: Ray Scott was term-limited. District 13: John Cooke was term-limited. District 30: Chris Holbert was term-limited, then resigned on May 31, 2022. Predictions
