Amendment 86 · Citizen-initiated constitutional amendment (needs 55% to pass)

Requirements for off-cycle congressional redistricting

Official ballot title (quoted exactly)

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?

Ballot title as printed in the 2026 State Ballot Information Booklet (Blue Book), Colorado Legislative Council Staff.

A YES vote means:

Any change to Colorado’s congressional map outside the regular once-a-decade schedule would need at least three public meetings and approval by the Independent Congressional Redistricting Commission and the Colorado Supreme Court.

A NO vote means:

The current requirements for redrawing congressional districts every ten years continue.

What it would change

  • What it does: re-enacts the current redistricting process and adds conditions for mid-decade map changes, including no dividing communities of interest or purposely favoring a party.
  • Taxes and fees: none.
  • Fiscal impact (Legislative Council Staff): about $370,000 in any year the commission must review off-cycle map changes.

Official arguments, summarized

Short neutral summaries of the arguments printed in the official voters’ pamphlet. The committees that wrote them are responsible for their content. Read the full text at the link below.

Argument for

Supporters say it guarantees public participation and independent commission review for any off-cycle change to congressional districts and keeps partisan politics out of the process voters created in 2018.

Argument against

Opponents say it would create an unnecessary barrier if voters ever want new congressional districts between censuses, and that the same commission should not control that process.
