President Donald Trump's political coalition, the improbable alliance of working-class voters, evangelical Christians and disaffected independents that propelled him back to the White House, is showing signs of fracture at a perilous moment. With the 2026 midterm elections on the horizon, four separate national polls now chart a dramatic collapse in independent support, with net approval ratings plunging by as much as 38 points since inauguration. At the same time, fear of inflation has reached a record high among American voters, a development that directly threatens the economic credibility Trump has long claimed as his own. Viewed from Washington, the numbers suggest that the president is entering the cycle with a weakened hand.

Economic anxiety sits at the heart of the shift. A new survey found that 43 percent of registered voters now rank inflation among their top three concerns, with one in five calling it the single most important issue. Among non-college-educated white workers — the backbone of Trump's electoral strength — faith in his economic management is eroding for the first time. Dissatisfaction in this group, which once backed him by more than 30 percentage points, has widened to between 14 and 30 points in recent assessments, according to polling from multiple outlets. Italian commentators, who have often framed Trump as the authentic democrat speaking for the grease-stained hands against a sterile oligarchy, may be observing the very material that could melt that image: when the bills bite, even cultural grievance loses its grip.

Unease is surfacing elsewhere in the coalition. Evangelical Christians, a pillar of Trump's electoral success, are increasingly troubled by the administration's posture on Iran and its immigration enforcement, with nearly half in a Reuters/Ipsos poll saying those policies fail to align with their religious understanding. A report in the Dhaka-based press underscores how this influential voting bloc, crucial in midterm turnout, is wavering. Meanwhile, analysts in Tehran dryly note the irony of a political honeymoon ending with the workers who helped build Trump's movement. Nor do the president's loudest defenders appear to have a persuasive counter-narrative: a sustained study by American pro-democracy groups found that warning Trump voters about authoritarianism largely falls flat, because the very institutions being defended are seen as illegitimate by those voters.

Into this volatile mix, Trump has injected a fresh wave of unsubstantiated election fraud claims, branding California's primary "rigged" and hinting at a repeat of the strategy that preceded the 2020 Capitol riot. Election experts warn that this posture poses a bigger threat to the integrity of the 2026 midterms than four years ago. The combination of a fracturing coalition, persistent inflation and a renewed assault on democratic norms leaves the Republican Party in a precarious position. While the president's base may hold, the defection of independents and a growing economic scepticism among working-class communities could reshape competitive House and Senate races. The months ahead will test whether the chemistry of grievance, once so potent, can survive the weight of material discontent.
