House Speaker Mike Johnson has voiced confidence that Republicans will not only retain but expand their House majority in November's midterms, pushing back against growing Democratic optimism about retaking Congress. With Republicans holding slim margins (a 53-47 Senate edge and an even tighter House majority), and nonpartisan forecasters increasingly favouring Democrats, the prediction comes as the GOP faces traditional midterm headwinds compounded by persistent inflation, high petrol prices linked to an unpopular war with Iran, and Trump's weak approval ratings.

Democratic leaders, including Senate Minority Leader Chuck Schumer, claim momentum on their side, while Johnson counters that left-wing primary victories have handed Republicans ammunition to paint Democrats as extremists. Mid-decade redistricting could net the GOP up to a dozen additional favourable House seats, though Democrats have expanded their target list to 58 Republican-held districts, including 12 in Trump-won territory. Recent Fox News polling shows three in four voters reporting financial hardship from inflation, 54% expecting the economy to worsen, and Democrats leading on the generic congressional ballot.
