A CNN data analyst delivered a grim assessment this week for Republicans facing voters in November, telling the network that President Donald Trump’s decision to engage militarily with Iran has cost him the coalition that powered his 2024 victory.
CNN chief data analyst Harry Enten appeared on the network on Aug. 11, 2026, showing numbers that reveal massive defections among working-class Americans and a complete reversal on which party voters trust to handle foreign threats. The analyst traced the collapse directly to an unauthorized military engagement paired with surging fuel costs that have undermined two pillars of Trump’s last campaign: economic relief and peace.
Gasoline has jumped from around $3 per gallon to over $4 since the conflict began, squeezing families who expected the opposite. Meanwhile, backing for the Iran policy among the most politically active voters has plummeted 24 percentage points over two years, according to CNN/SSRS polling. Enten called it “a giant fall.”
National Security Advantage Erased
The most dramatic reversal involves defense and foreign policy, territory Republicans dominated for decades. A Reuters/Ipsos survey showed the GOP with an 18-point lead over Democrats on handling wars, conflicts and terrorism in January 2025. Democrats now lead by two points, a 20-point shift driven by the Iran confrontation.
Public pessimism about the outcome is widespread. Fox News polling found just 27 percent of voters across all groups expect a favorable agreement between the United States and Iran, with Republican confidence reaching just 41 percent. Enten said the fact that every group polled fell below 50 percent was the most shocking finding. He explained that the public lacks clarity on the conflict’s purpose or path to resolution.
He warned GOP congressional candidates not to assume they can distance themselves from the president’s struggles. According to Enten, the president’s falling support will drag down Republican candidates as well, tying their fates together on this matter.
Working-Class Defections Accelerate
The hemorrhaging is most severe among voters without college degrees, the demographic that formed Trump’s core. In a segment on Aug. 7, Enten showed host John Berman a Marquette University Law School poll tracking Trump’s net favorability with non-college adults from plus-six in October 2024 to minus-22 in July 2026. “Down we go into the Atlantic Ocean,” he said.
Enten’s polling average told a parallel story. Trump won non-college voters by 13 points in 2024; his current running average shows him losing them by 19 points. According to Enten, the demographic foundation of Trump’s presidential campaign is now turning against him and rejecting the MAGA movement. He argued the reversal explains Trump’s serious political challenges, since the opposition now extends beyond college-educated voters to his former base.
The movement is already reshaping congressional contests. Non-college voters preferred a Republican-controlled House by plus-13 after the 2024 election. That cohort now leans Democratic by a single point, a development Enten said should terrify Republicans running in November.
Rebuttals and Warnings
White House spokesperson Kush Desai pushed back on the economic critique, telling the Daily Beast that fuel prices returned to previous levels after the administration signed its preliminary memorandum of understanding. He forecast that inflation would decline once more after Trump achieves a settlement with Iran. GOP strategist David Winston offered a more cautious assessment, noting that Democrats could trigger a Blue Wave if they maintain economic advantages and double-digit leads with independent voters.
Enten suggested the fallout reaches beyond November to an honor Trump has openly pursued. Cash prediction markets show the president’s chances of winning the 2026 Nobel Peace Prize have dropped from 33 percent less than a year ago to just 4 percent now. According to Enten, the Iran conflict has pulled those prospects down along with it.
The contrast with recent history is stark. In July 2026, Trump shared a segment where the analyst praised his primary dominance, highlighting how Trump’s endorsement boosted South Carolina Sen. Darline Graham Nordone’s primary victory odds from 14 percent to 80 percent on the prediction market Kalshi. Graham Nordone had no prior electoral experience before being appointed to her late brother Lindsey Graham’s seat and subsequently qualified for a Republican primary runoff versus Rep. Ralph Norman. Enten noted Trump’s exceptional success in Senate primaries starting in 2022, when his endorsements secured wins in 95 percent of open-seat contests.
That command over Republican primaries, however, has not translated into general-election strength. With the midterms approaching in November, the same analyst who once documented Trump’s grip on his party is now tracking how quickly that grip is slipping in the broader electorate.
