The polls behind it

13 polls · 6 in today's forecast · newest first

Dimmed polls are more than 61 days old. They stay on the record, but today's forecast no longer counts them. Each pollster name links to the poll's source; the grade under it is its VotePredictor grade from past elections. Margin is the poll as published. The ± under the sample size is the 95% margin of error on each candidate's share, from the sample size (the gap between them is about twice as uncertain). VotePredictor adjusted (“Our adj.” on small screens) is not a poll: it is our correction of that poll, for its pollster's record in past elections and for registered-voter or all-adult samples. It is the number our forecast reads.

The source we collect records each outlet's rating category, not a probability; some of these outlets run models with their own numbers on their sites. The ≈ figure is the standard conversion of the category (Toss-up 50%, Tilt 60%, Lean 75%, Likely 90%, Solid 99%), the one our scorecard grades them on, not a number they published. They remain independent of VotePredictor. Sources and update dates ↗

Independent models

Win probabilities published by independent statistical models, shown with credit as their terms allow: Who Shows Up (whoshowsup.net), by Kurt Wirth. These are their numbers, not ratings converted by us, and not VotePredictor's. The better-known model forecasters (Decision Desk HQ, FiftyPlusOne, Silver Bulletin, the Economist) don't permit republishing their probabilities, so they appear above by rating only.

Past results

Every U.S. Senate election in Massachusetts we hold a result for. A state elects two senators on separate cycles, so this covers both of its seats, not only the one on the ballot in 2026.
