Three governor’s races are inside the margin, and the polling is telling two different stories

Three governor’s races are close enough that the polling method changes the answer. In each, live-caller surveys and online panel surveys differ by between six and nine points — a gap larger than the reported margin of error for either.

When two credible methods disagree by more than their stated uncertainty, at least one of them is wrong in a way its own math does not capture. Both were within two points of the result in the same three states four years ago.

Where the gap sits

The divergence is not spread evenly. Crosstabs shared with MNC News by two firms show it concentrating among voters under 35 and, separately, in fast-growing exurban counties. Both are groups where the modeled electorate does most of the work, because the historical turnout record is thin.

A pollster at one of the firms put it plainly: “We are not measuring different opinions. We are assuming different electorates, and the assumption is doing more work than the interviews.”

When the crosstabs disagree more than the toplines, the disagreement is about who votes, not about what they think.— A pollster whose firm runs both methods

What to watch instead

Analysts who have stopped trusting the toplines suggested three indicators that do not depend on turnout modeling: early vote composition by age once it begins, party registration changes in the exurban counties, and the size of the undecided share four weeks out, which historically breaks late and unevenly.

• States affected: three, all with races inside the reported margin
• Gap between methods: 6 to 9 points
• Concentration: voters under 35 and fast-growing exurban counties
• Four years ago: both methods finished within two points in these states

Both firms said they will publish their turnout assumptions alongside their final surveys — a practice that used to be unusual and is becoming standard, largely because gaps like this one keep appearing.
