Simulated poll · 21–22 June 2026

These numbers come from a computer, not from asking people. In June 2026 we asked AI stand-ins, not real voters, how they would vote. Each stand-in is built from public census and voter records. No real votes were counted, nobody was asked, and this does not predict the election.

Why the model expects this result

A typical precinct in this model sits at 65.3% Democratic on the two-party vote. This precinct's neighbourhood traits move that to 74.5%.

What pushes it toward the Democrats: Businesses per 1k residents, % without HS diploma and % uninsured.

What pushes it toward the Republicans: % aged 65+.

It projected came out at 72.2%, close to what the traits suggest.

How each fact changes the guess for this areaA typical area starts at 65.3 per cent Democratic. Pushing up: Businesses per 1k residents 3.0 points, % without HS diploma 2.1 points, % uninsured 1.6 points, % mobile homes 1.0 points, Population density 0.9 points. Pushing down: % aged 65+ 0.7 points. All the remaining facts together move it up 1.4 points.

Across all precincts this model explains about 40% of the variation in results, and is typically off by 10 points for any one precinct. The model only knows facts about the area, such as age, pay and housing. It knows nothing about the people standing for election, what they said, what mattered locally, or who turned out to vote. That is why the real result can be a long way from its guess. These are patterns across whole areas. They do not tell you how any one person voted, and they do not show that one thing causes another. When two things go together, such as low pay and low rents, the model cannot tell them apart, so it shares the credit between them.

How does this area compare with the rest of the state?

One row for each fact. Every dot is an area in this state, placed by how far that fact moved the guess there. This area is the ringed dot.

Each fact, with one dot per areaOne row for each fact the model used. Every dot is an area. Dots on the left mean the fact pushed that area towards the Republicans, dots on the right towards the Democrats. Darker dots mean the fact runs higher there. The ringed dot is this area.

Every other dot is one of the 564 areas in Maine that the same computer looked at. For each fact we only show the areas where it was one of the six that mattered most, so you are seeing that fact where it counted, not everywhere.

How the model was built

We give a computer about 20 facts about each area and ask it to guess how the area voted. It is never shown any votes. The facts are things like age, race, pay, jobs, health cover and the kind of homes people live in. They come from the 2020 Census and from other government figures.

To check the guesses are fair, we train the computer on some states and then test it on states it has never seen. That way it cannot simply remember the answer.

Each bar shows how much one fact moved the guess up or down for this area. Some facts are measured for the whole county, so they are the same for every area in that county. Where two neighbouring areas differ, it is their own 2020 Census figures that pull them apart.

For the technically minded: the model is gradient-boosted trees (XGBoost), the target is the two-party Democratic share, the bars are SHAP values, and it is validated by holding out whole states. County-level inputs include the Census/CDC Social Vulnerability Index 2018–2022, County Business Patterns and wage data.
