Recent election results

Colorado state senators are elected to staggered four-year terms. The old 27th district held elections in presidential years, but the new district drawn following the 2020 Census will hold elections in midterm years.

2022

The 2022 election will be the first one held under the state's new district lines. Incumbent Senator Chris Kolker was redistricted to the 16th district, which won't be up until 2024; State Rep. Tom Sullivan is running for the 27th district instead.^[7]
