There is a voter the polls cannot see, and in all three elections with Trump on the ballot that voter decided the outcome.
This voter does not lie. This voter does not answer. Does not pick up a call from an unknown number, does not fill out the online panel, does not tell a stranger how they will vote. And when the pollster weights the sample, this voter gets replaced by someone who looks the same on paper but does not vote the same.
In 2016 the state polls missed this voter in Wisconsin, Michigan and Pennsylvania. In 2020 the American Association for Public Opinion Research documented the largest national polling error in forty years, all of it in one direction. In 2024 it happened again. Smaller, same direction.
Brazil has its own version. In the first round of 2022, the traditional pollsters gave Jair Bolsonaro several points less than he actually got. The closest was AtlasIntel, which today has his son tied with Lula.
And there is one vote I know well because it belongs to many of my readers: the Latino vote. In 2024 nearly half of Latino voters went Republican, and almost no poll saw it coming at that size.
My forecast does not contradict the polls. It corrects them for the size of the vote that doesn't answer.
It is worth stating plainly what the models say today, because my numbers break from them. Decision Desk gives Democrats a 55 percent chance of winning the Senate and a 76 percent chance of winning the House, with 234 seats. Nate Silver has the generic ballot at D+9.6. AtlasIntel has Lula and Flávio tied in the runoff. My three numbers depart from that consensus in a single direction, for a single reason.
