PollsterSampleEndedYesNoUndecidedYes, adjusted
No public polls of this measure. The forecast rests on how comparable measures have run and how it reached the ballot.
How this is built
Proposition 133 is forecast as a criminal justice measure whose Yes vote leans Republican. Comparable measures from 2018 to 2024 set how far its Yes share moves with Colorado's partisanship and with each county's 2024 presidential vote, and how it reached the ballot moves it further. Polls then pull the forecast toward them by recency and size, after splitting undecided voters two to one for No. Sources: news.ballotpedia.org, koaa.com, coloradodems.org. All measures.
