Iowa Governor Race Shifts as CNN Data Shows Trump Losing Grip on Heartland Voters
New polling data suggests President Donald Trump's standing with a key voter bloc is crumbling, and the fallout could reshape Iowa's political landscape heading into the 2026 midterm elections.
CNN chief data analyst Harry Enten revealed Tuesday that Trump's support among white non-college voters, the demographic that powered his three presidential campaigns, has flipped into negative territory. The shift comes as Iowa Democrats see a rare opportunity to capture the governor's mansion for the first time in two decades.
What the latest polling shows about Trump's support in the heartland
Enten appeared on CNN News Central to break down the numbers, noting that Trump now sits at minus 2 points with white non-college voters, a dramatic 27-point swing from his 25-point lead over Kamala Harris in October 2024.
“They were the heartbeat of President Trump's three presidential campaigns,” Enten said. “And right now, the heartland is ripping the heart out of Donald Trump's presidency.”
The decline is historically significant. Enten noted that Trump was more reliant on this voter group than any previous Republican president, including George W. Bush, Dwight D. Eisenhower, and Ronald Reagan. Now he holds the lowest approval rating among them at this point in a second term.
Economic concerns driving the political shift
Inflation remains the central issue driving voters away from the president. Enten pointed out that Trump won reelection largely because voters were frustrated with Joe Biden's handling of the economy and cost of living.
The numbers tell a stark story: Trump's net approval on inflation among white non-college voters has collapsed from plus 24 points to minus 39 points, a 63-point swing on the very issue that secured his second term.
“That's a change of 63 points in the wrong direction, on the key issue that got Donald Trump reelected to a second term, among the key group that got him reelected,” Enten said.
What this means for Iowa's 2026 governor race
These trends are fueling Democratic hopes in Iowa. Enten suggested that Rob Sand, the state auditor, now looks poised to become Iowa's first Democratic governor in 20 years.
The president's recent promise of a $15 billion steel plant in Iowa appears aimed at shoring up support in a state that has been reliably Republican in recent cycles. However, the polling suggests economic anxieties may be overriding those efforts.
Historical precedent offers little comfort for Republicans. Enten recalled that George W. Bush's party lost both chambers of Congress in the 2006 midterms when similar voter dissatisfaction emerged during his second term.
What Iowa voters should watch heading into November
For Iowans, the coming months will reveal whether these national trends translate into local results. Key factors to monitor include:
- Gas price movements and their effect on consumer confidence
- The administration's handling of the situation in Iran
- Whether the proposed steel plant materializes into jobs and investment
- How Republican candidates navigate the president's declining numbers
The midterm elections are historically challenging for the party holding the White House, but the magnitude of Trump's slide with his core constituency suggests Iowa could be in play in ways it has not been in years.
As the campaign season heats up, Iowa voters will ultimately decide whether these polling trends become reality at the ballot box.
