Polls Underestimated Democratic Gains Across Key Midterm Races

Comparisons of final RealClearPolling averages with reported election results show sizable polling errors in several high-profile races. Democrats won Senate seats in Texas, South Carolina, Georgia, North Carolina and Maine, among other states, and captured the Texas and Georgia governorships. Democrats also took control of the House and won at least 54 Senate seats; Alaska and Mississippi had yet to be called by November 4.

The largest listed Senate miss was in Texas. The final average gave Democrat James Talarico a 2.6-point lead over Republican Ken Paxton, while the Associated Press’s reported result put Talarico ahead by 12.1 points. In the Texas governor’s race, the average favored Republican Greg Abbott by 2.3 points, but Democrat Gina Hinojosa led the reported count by 7.1 points.

In South Carolina, the average put Republican Darline Graham Nordone ahead of Democrat Annie Andrews by 2.6 points; Andrews’ reported lead was 4.4 points. Georgia’s Senate polling favored Democrat Jon Ossoff, but by 8.6 points, compared with a reported 18-point victory. North Carolina’s Roy Cooper and Georgia gubernatorial candidate Keisha Lance Bottoms also won by wider margins than the averages suggested.

Other listed misses included Iowa’s tied Senate average, followed by Democrat Josh Turek’s 4.1-point lead, and Maine, where Troy Jackson defeated Republican Susan Collins by more than six points, against an average showing Jackson ahead by 3.6 points. The comparisons were preliminary as ballots continued to be counted in several states.

A Northeastern University political scientist said polling gaps can reflect late campaign developments or flaws in the surveys. Another polling analysis judged the polls broadly successful in signaling Democratic gains, while noting that they were not precise in some Senate contests. Polling averages can reduce the effect of outlying surveys, but do not eliminate sampling problems.

Polls Missed the Scale of Democratic Voters’ Rebuke

The 2026 midterms delivered a clear Democratic surge that many final polls failed to measure. In Texas, averages showed Republican Greg Abbott ahead for governor and gave Democrat James Talarico only a narrow Senate lead. The reported results instead showed Gina Hinojosa ahead by 7.1 points and Talarico by 12.1.

The pattern crossed state lines. South Carolina’s final Senate average favored Republican Darline Graham Nordone, but Democrat Annie Andrews won by 4.4 points. In Georgia, Jon Ossoff’s 18-point reported Senate victory was more than twice the lead polls had projected. Roy Cooper in North Carolina and Keisha Lance Bottoms in Georgia also outperformed their averages.

Democrats captured Senate contests in Texas, Kansas, Ohio, South Carolina, Iowa, Maine and North Carolina, while retaining competitive seats in Michigan and Georgia. They secured at least 54 Senate seats as Alaska and Mississippi remained unresolved on November 4, and took control of the House.

The results expose the limits of surveys that understated Democratic support across consequential contests. Polls may have broadly pointed toward Democratic gains, but broad direction was not enough for voters, campaigns or forecasters trying to understand the scale of the shift. A political scientist cited late developments and survey shortcomings as possible sources of polling gaps. Ballot counting was still underway in several states, leaving these comparisons preliminary.

Polling Misses Were Real, but the Broad Midterm Signal Held

The 2026 polls were imperfect, but their broad warning of Democratic gains proved right. Democrats won control of the House and at least 54 Senate seats, while final averages had generally indicated an unfavorable midterm environment for the party holding the presidency.

Some individual forecasts were badly off. Texas polling showed Republican Greg Abbott ahead for governor and Democrat James Talarico narrowly ahead in the Senate; the reported results put Gina Hinojosa ahead by 7.1 points and Talarico by 12.1. In South Carolina, an average favoring Republican Darline Graham Nordone missed Democrat Annie Andrews’ 4.4-point lead. Georgia’s Senate average also substantially understated Jon Ossoff’s reported margin.

Those failures matter, especially when polls shape campaign spending and expectations about control of Congress. But an inaccurate margin is not the same as getting the overall direction wrong. A polling analysis found that surveys generally signaled Democratic gains, even if several races exposed substantial uncertainty and persistent challenges in reaching voters.

The comparisons remain preliminary as ballots are counted in some states. Poll averages can reduce the influence of outlier surveys, but cannot guarantee precision. The 2026 results offer a case for treating polling as an imperfect guide to voter sentiment—not as a promise that every race or margin will be called correctly.
