The polling industry is running the same play it has run for three straight cycles, and a new breakdown of the historical record shows exactly how often that play has been wrong.
Echelon Insights pollster Patrick Ruffini, writing at The Intersection, released an infographic this week measuring Democratic two-party Senate polling averages in Iowa, Michigan, and Ohio across 2018–2024, taken at the same point on the calendar we are sitting on now, 33 days before Election Day. The dotted line on his chart is today’s point in the 2026 cycle.
The result is brutal for the people still treating late-September surveys as prophecy.
93 percent of the polls overstated the Democrat. The average miss at 33 days out was D+6.2 points. In midterm years alone, the average miss was D+6.6 points.
Ruffini pulled the numbers from the FiveThirtyEight archive, stripped partisan house effects, and lined them up against certified results from the MIT Election Lab. He posted the chart on October 1.
The races the media wrote off tell the story:
- Iowa, 2020 — Greenfield (D) vs. Ernst (R): Polls at 33 days had Democrat Theresa Greenfield up 2.4. Sen. Joni Ernst won by 6.8.
- Iowa, 2022 — Franken (D) vs. Grassley (R): Already R+7.7 at 33 days. Sen. Chuck Grassley finished R+12.2.
- Michigan, 2018 — Stabenow (D) vs. James (R): Polls had Debbie Stabenow up 14.0. She won by 6.6.
- Michigan, 2020 — Peters (D) vs. James (R): D+6.5 in the polls. Gary Peters won by 1.7.
- Michigan, 2024 — Slotkin (D) vs. Rogers (R): D+5.5 at 33 days. Elissa Slotkin scraped by Mike Rogers by 0.3.
- Ohio, 2018 — Brown (D) vs. Renacci (R): Sherrod Brown was up 16.3 in the polls. He won by 6.8.
- Ohio, 2022 — Ryan (D) vs. Vance (R): Tim Ryan was essentially tied to slightly behind. JD Vance won by 6.1.
- Ohio, 2024 — Brown (D) vs. Moreno (R): Polls had Brown up 0.4. Bernie Moreno beat him by 3.8.
That is the pattern. Democrats look alive, sometimes comfortably ahead, five weeks out in the industrial Midwest.
Then the electorate shows up and the Republican wins, or the Democrat’s “landslide” collapses into a squeaker. Ernst was supposed to be in trouble. Moreno was supposed to lose to a three-term incumbent. Both are in the Senate.
Ruffini had already flagged the broader problem in August. Across 3,312 Senate polls from 2018, 2020, 2022 and 2024, the average error was D+3.7, 73 percent of individual polls overstated the Democrat, and the miss peaked around D+5.9 in late July before narrowing toward Election Day.

NRSC National Press Secretary Bernadette Breslin did not bother with the soft version.
“Democrats should think twice before relying too heavily on the same rosy polling that has historically written Republicans off cycle after cycle, only to be proven wrong come Election Day,” Breslin said, amplifying the findings.

Michigan already supplied a fresh exhibit, and it was not even a general election. In the August 4 Democratic Senate primary, polls had socialist Abdul El-Sayed, the Bernie Sanders-backed former Wayne County health director, leading Rep. Haley Stevens by double digits.
The Washington Post reported the industry overestimated his lead by about 12 points. He won by roughly a point.
The New York Times and National Review both walked through the miss: primary pollsters guessed wrong on who would actually show up, and the enthusiastic online left took the surveys while working-class and Black Democrats in Detroit, Saginaw and the rural counties voted for Stevens.
That is the same El-Sayed now being sold as neck-and-neck with Republican Mike Rogers for the open Michigan seat. The same Rogers who lost to Slotkin by three-tenths of a point after the polls had him down more than five.
The Gateway Pundit has been on this for years. In September, CNN chief data analyst Harry Enten warned on air that the polls underestimated Republicans in four of the last six elections, including a 3-point Senate miss in 2024, and showed what a 2-to-4-point GOP overperformance would do to the 2026 map, Michigan flips, Ohio and Iowa stay red, and the Democratic Senate dream goes into Lake Erie.
In 2024, pollster John McLaughlin told Just the News the surveys pumping up Kamala Harris were oversampling Democrats on purpose.
Enten has also undercut the media’s favorite 2026 story, the supposed enthusiasm gap. CNN’s own data put Democrats and MAGA Republicans at the same place: 71 percent of each group say they are certain to vote. Enten’s word for it was “simpatico.”
On a red-leaning Senate map where registered Republicans already outnumber registered Democrats in the states that matter, parity in the base is not the blue wave the cable panels have been selling.
President Trump said the quiet part at his Ohio rally this weekend, campaigning for Sen. John Husted against Brown’s comeback bid and for Vivek Ramaswamy: the polls have always underestimated MAGA.
They tried it in 2016. They tried it in 2020. They tried it in 2022. They tried it in 2024, when he won every swing state. They are trying it again, 33 days out, in the same three states, with the same error bar.
Voters who remember Ernst, Vance, and Moreno do not need another panel of experts to explain what comes next.
On Sunday, President Trump told supporters that Republicans are going to “win big” against the Democrats in November and “shove it up their ass.”
“The Polls have ALWAYS underestimated MAGA. They try to suppress the Vote, but I won all 7 Swing States, the Popular Vote, 86% of Counties, and 99% of Primaries this year. I AM ON THE BALLOT! President DONALD J. TRUMP
From Dick Morris: “Since November of 2025 in monthly polls by McLaughlin, your job approval rating has always been between 47 and 50 percent. I have never seen anything like that in fifty years of polling. Almost every politician sees his numbers rise and fall each month but not you.
You won the election in 2024 with 49.8 percent of the popular vote and the latest McLaughlin Poll, taken this month, has your job approval at 49% – the exact same as your vote share. No other political figure has ever had this level of consistency in his ratings.
Through the Iran War and gas price rises and falls, your job approval is the same. It never changes. And 49% is enough to win – look at how that level of vote won in 2024! In the same Mclaughlin Poll, the generic ballot is 50-48 Democrat. That is also enough to keep the House Republican. Past history indicates that anything less than a four point margin for Democrats likely points to a Republican House victory. And almost all polls are showing Republican gains in the generic ballot.”
