American voters heading into this fall’s midterm elections are overestimating local gas price increases at alarming rates, creating a severe political vulnerability for Republicans struggling to maintain congressional control amid the ongoing war with Iran. According to a new POLITICO Poll analysis of granular pricing data, three out of five Americans believe fuel prices in their area have risen significantly more than they actually have—a psychological disconnect that threatens to mobilize Democrats and fracture the GOP coalition come November.
Psychological Reality vs. Economic Data
While average gas prices peaked at $4.50 per gallon in mid-May before dipping to $3.78 in July, public perception remains anchored at peak frustration levels. The analysis, which paired survey responses from Public First with zip-code-level pricing data from OPIS, revealed that roughly one in four Americans believe local gas prices have jumped by $3.00 or more per gallon since President Donald Trump took office.
In reality, no zip code in the entire nation experienced an increase of that magnitude over the 18-month period. This perception gap is particularly pronounced among former Vice President Kamala Harris supporters, 70 percent of whom overestimated local price spikes, compared to 54 percent of Trump voters.
Data indicates that these distorted economic perceptions strongly correlate with broader dissatisfaction. Across the nation, 57 percent of Americans report that the cost of living is worse than they can ever remember it being, with those overestimating gas prices twice as likely to hold that view.
Midterm Vulnerabilities and Coalition Fractures
The persistent anxiety over energy costs is translating directly into voting behavior, with 46 percent of Americans reporting that gas prices will influence their choices at the ballot box this fall. Among those who say fuel costs will impact their vote, nearly 40 percent are considering casting a ballot for a different party than usual.
This dynamic exposes a growing rift within the Republican base. According to the poll, 57 percent of non-MAGA Republicans and 49 percent of self-identified MAGA Republicans are considering voting against their usual party alignment, signaling widespread economic vulnerability.
