Donald Trump used an Oval Office interview with the "Wall Street Journal" to tout what he called the greatest economy in history while candidly warning Republicans could still lose the 2026 midterm elections, acknowledging that many voters are not yet feeling the gains he promises from multibillion-dollar investments in factories, AI projects, and energy production. He blamed persistent inflation and high living costs on Democrats and Joe Biden, even as polling such as an AP-NORC survey and a University of Chicago study shows his economic approval stuck around 31 percent, turning what was once considered his strongest issue into a growing vulnerability. Citing historical midterm losses for parties in power, rare cases like Bill Clinton and George W. Bush gaining House seats, recent Democratic wins by Eric Gisler in Georgia and Eileen Higgins in Miami, and looming fights over tariffs at the Supreme Court and redistricting in Republican states, Trump described the coming midterms as "statistically very tough" and said he could not predict when voters would truly feel the benefits of his agenda.
