NPR Editors Warn That State-Level Polling Quality Has Deteriorated Amid Local News Cuts

National horse-race polling has remained largely accurate for the 2026 midterms, with only a slight underestimation of Republican turnout, according to Domenico Montanaro, NPR senior political editor. However, state-level surveys have suffered from a decline in quality, a shift Montanaro attributes to the financial strain on local journalism.

Local newspapers and television stations lack the budget of national outlets to fund rigorous and frequent polling, Montanaro said. This financial gap has allowed low-budget "junk polls" and even a few fake surveys to enter the data stream in state contests.

Montanaro noted that the public often expects a precision from polls that the methodology does not support. A poll with a margin of error of plus or minus 3 or 4 percentage points actually represents a range of 6 to 8 points. In close races, this fuzzy range is the accurate picture, even if it feels less specific to voters.

The correspondents advised that polls should be treated as one tool among many rather than the sole indicator of election outcomes. They emphasized the need to mix polling data with historical context, direct reporting on campaigns, and on-the-ground observation.

Campaigns and corporations spend millions of dollars on polling to determine where to deploy resources and which messages to use, Montanaro said. These entities use the same external pollsters that news outlets consult, suggesting the data has utility despite its imperfections.

NPR congressional reporter Sam Gringlas described the current midterm cycle as offering a more intimate view of candidates than presidential years. Early in the cycle, reporters can observe House and Senate candidates in settings such as antique shops, farmers markets, and family farms.

These environments allow for direct interaction and questioning, unlike the stadium-sized venues and heavy security that characterize presidential rallies, Gringlas said. This proximity provides a clearer view of how candidates interact with voters.

Tamara Keith, NPR senior political correspondent, highlighted the messiness of Nevada's 2nd Congressional District as a focal point for curiosity. Trump won the district by 14 points in the most recent election, and it has been represented by a Democrat for less than 40 years of its existence.

The Republican nominee, backed by Trump, moved to the district specifically to run for Congress and has faced scrutiny over personal history, including blaming his grandchildren for a misstep in an interview. The retiring Republican congressman has criticized the nominee publicly and stated he voted for a Libertarian candidate.

The Nevada Democrat is a former Miss Nevada turned state legislator who has run a strong campaign. Keith said the race remains a Republican favorite but is being watched closely due to the unusual dynamics.

Voters in several states will also weigh in on redistricting and voting methods. In Maryland, a measure to allow Democrats to add one seat is unlikely to pass, a surprising outcome for a Democratic state. Colorado voters are considering a measure to make mid-decade redistricting harder, while Missouri voters will decide on a redistricting map that could help Republicans flip a seat.

Alaska voters will again decide whether to keep their top-four nonpartisan primary system and ranked choice voting. Past cycles have shown voters consistently supporting this structure despite close votes on the issue each time.
