The race, in brief

Colorado elects a governor on November 3, 2026, in an open seat: Democratic governor Jared Polis is ineligible for a third consecutive term. The text says Republicans have not won a Colorado governor's race since 2002 nor any statewide office since 2016. The state profile on file records a college share of 0.4, a Hispanic share of 0.2 and a median age of 37.5.

The Democratic nominee is attorney general Phil Weiser, who beat U.S. senator Michael Bennet in the June 30 primary, 56.9% to 43.1%; his running mate is Jefferson County commissioner Lesley Dahlkemper. The Republican nominee is Victor Marx, described as a ministry leader, who won a three-way primary with 39.9% to Barbara Kirkmeyer's 39.4% and Scott Bottoms's 20.8%, a margin of 208,455 votes to 205,990. His running mate is George Markert. Former U.S. representative Greg Lopez is running as an Independent, and Unity, American Constitution, Libertarian and Approval Voting candidates are also on the list.

All seven raters listed call the race D; the dates run from September 3, 2025 (Inside Elections) to September 23, 2026 (Decision Desk HQ). The text lists no general-election polls and no fundraising figures.

A shift of 5.9 points toward the Democrats from 2016 to 2024. county returns summed; MEDSL county file (2016), an MIT-licensed county file (2020, checked against certified state results) and MEDSL precinct returns (2024). For a district split across counties this is an estimate, and where the state published the exact 2024 figure for these lines, that exact figure is the one the model uses.

Has anyone polled it?

We hold no published poll of this general election. A search of aggregators, pollster releases, university polls and local news on 2 October found none (primary polls exist for some races and are not this contest). That is what we could find, not proof that no poll has been conducted. When one is published it enters the poll model and this page gains a nowcast.

Margins and probabilities are for Phil Weiser. With no polls, this is the fundamentals forecast alone: the state's own past results for this office and for president, its demographics, economy, religion and government employment, the candidates' incumbency, experience and money, and the national environment for this midterm.

How wide is the range?

In 8 of 10 simulations the margin falls between +5 and +39 points. The spread is the fundamentals model's own measured error (sd 13.4 points), not a guess: a forecast without polls is uncertain and is shown that way.

How accurate is a fundamentals-only forecast?

Tested on past races without letting it see them: across 175 Senate and governor races in 2016-2022 it missed the final margin by 8.3 points on average, and by 6.7 points across 35 races in 2024. Our poll-based forecast missed by 5.4 on the same races. Most races it is used for here are lopsided enough that an 8-point miss would not change the winner.

Where did every number come from?

Run 37c65dcd, single_race_latent/0.8.1, as of 2026-10-01 23:02 UTC, basis: ground-up prior only, no polls.
