Midterm Election FAQ: Can We Trust the Polls? Are Democrats Doomed?

We’re coming down to the wire, and Democrats' hopes of holding onto the Senate and the House are fading fast. Two months ago, the story was that Democrats seemed poised to pull off an upset and hold onto the Senate despite the fact that the party in power almost always loses seats in the midter

Episode Summary

Executive Summary: The episode examines two linked crises ahead of the U.S. midterms: Republicans’ late surge and the declining reliability of modern polling. Pollster Kristen Soltis Anderson argues that polling faces structural problems—low response rates, changing technology, and partisan/nonresponse biases—while the election itself is being pulled by fundamentals like inflation, gas prices, incumbency, and candidate quality. Georgia and Pennsylvania emerge as the pivotal Senate battlegrounds, with Trump’s influence still central to GOP candidate selection and voter perceptions.

Main Topics: Polling reliability is deteriorating (Priority: 5/5): Anderson says modern polling is in a transitional, experimental phase after repeated misses in 2016 and 2020, with pollsters still searching for a durable fix to nonresponse and sampling bias. Why polling used to work better (Priority: 5/5): The discussion contrasts the landline era—when voters were easier to reach and response rates were much higher—with today’s fragmented communication landscape and greater difficulty building representative samples. Republican undercount and social trust bias (Priority: 4/5): Anderson explains that Republicans are often underrepresented because GOP voters are now more likely to be non-college educated and lower in social trust, both traits associated with lower survey participation. Republican late surge in the midterms (Priority: 5/5): The conversation attributes the GOP’s recent gains to a reassertion of political fundamentals: inflation, gas prices, and the usual midterm penalty for the party in power, after Democrats benefited from a favorable summer. Georgia and Pennsylvania as Senate deciders (Priority: 5/5): Georgia is framed as uniquely chaotic because of its runoff rules and third-party candidates, while Pennsylvania is seen as competitive but with Fetterman still having a narrower edge than some polls suggest. Trump’s role in GOP talent selection (Priority: 4/5): A major theme is whether Trump helps or hurts Republicans. Anderson notes Republicans generally still think he helps, even as his preferred nominees may be weaker in general elections than the party’s structural advantage would suggest. Candidate quality versus party fundamentals (Priority: 4/5): The episode argues that Republican structural advantages may be offset by flawed nominees like Herschel Walker, Dr. Oz, and Doug Mastriano, which could determine whether the GOP fully capitalizes on favorable conditions.

Key Arguments: Modern polling is less trustworthy because fewer people respond, technology has changed, and pollsters are forced to make increasingly difficult assumptions to reconstruct the electorate. Polling errors are now more visible and more disruptive because punditry and media ecosystems amplify even small misses into major narratives. Republicans are underpolled in part because their coalition now overlaps with groups that are harder to reach and less likely to trust or engage with pollsters. The GOP’s recent improvement in the midterms is less a new Republican breakout than a return to fundamentals such as inflation and the party-in-power penalty. Democrats’ summer advantage likely reflected a favorable sequence of events—Dobbs, lower gas prices, Trump scandals, and Biden legislative wins—that may not persist. Georgia is especially volatile because runoff rules and third-party candidates make a 50% threshold hard to reach, increasing the odds of a prolonged fight. Trump remains highly influential inside the GOP because many Republican voters still believe he is helping the party, even if his nominees can be electorally flawed. Candidate scandals matter less when voters already view the candidate as flawed or when trust in media and political messaging is low.

Data Points: 538 Senate probability for Democrats in August: 80% - Used to show how quickly Democratic Senate prospects deteriorated. Polling response rate in the landline era: About 3 to 4 out of 10 people - Illustrates how much easier it was to conduct surveys when landlines were common. 2016 election polling error: Off by 12 points in the 1936 election; nearly 10 points in 1948; much smaller by the late 1980s and mid-1990s - Historical comparison of polling accuracy over time. Republicans saying Trump helps the party: 61% - Echelon polling result cited by Anderson about GOP views of Donald Trump. Republicans saying Trump hurts the party: 27% - Shows that only a minority of Republicans believe Trump is making things worse. Pennsylvania race polling example: Fetterman up by about 6 in a CNN poll - Referenced as a sign that Oz’s surge may be limited or variable. Mastriano polling gap: Down by almost double digits - Used to explain why the Pennsylvania governor’s race appears much less competitive than the Senate race. Electoral rarity of poll errors: Two or three points - Anderson notes that even small misses now trigger major alarm and media scrutiny.

Pivotal Quotes: "I think Ann Seltzer's take on this as a doomsday clock. Maybe I wouldn't use exactly the same metaphor." — Kristen Soltis Anderson: On the state of polling and the anxiety many pollsters feel after repeated misses. "The polling world is in the, we are developing an experimental cure. We're not sure if it's going to work, and we don't totally know what the side effects are, type mode." — Kristen Soltis Anderson: Describing how pollsters are still testing fixes rather than having solved the post-2020 polling problem. "I think gas prices explain everything." — Derek Thompson: A framing prompt for discussing whether inflation and fuel costs are the dominant driver of midterm dynamics.

Implications: Polling should be treated as informative but unstable, especially in close races. For the GOP, Trump’s hold on the party may secure loyalty while risking weaker nominees. For voters, late shifts driven by inflation and turnout could still reshape control of Congress.
