The ballot question
Shall there be an amendment to the Colorado Constitution concerning congressional redistricting, and, in connection therewith, reenacting the current process for congressional redistricting in the Colorado Constitution and prohibiting modifications to a final map unless at least three public meetings are held, the modifications do not have the effect of dividing communities of interest or purposefully favoring one political party, and are approved by the congressional redistricting commission and the Colorado Supreme Court?
What a vote does
- A yes vote means
- Sections 44 through 44.6 of article V are repealed and reenacted. A final congressional map could not be changed for the 2028 election or later unless the redistricting commission approves the change after at least three public meetings and the Colorado Supreme Court adopts it.
- A no vote means
- The measure is not enacted. The congressional redistricting sections of the state constitution stay as they are, and no new approval requirement applies to changing a final congressional map.
