WASHINGTON — House Republicans' four-seat majority is at risk in the November midterm elections, now just 100 days away. The party faces widespread retirements and internal divisions as President Donald Trump's approval ratings fall among crucial voter blocs. Democrats have overperformed in recent off-year and special elections, signaling a difficult environment for the GOP.

Trump's job approval has eroded sharply among groups that backed him in 2024. Only 35 percent of Hispanic voters, 28 percent of young adults and 27 percent of independents approve of his performance, according to recent polling.

That erosion has translated into a significant generic ballot lead for Democrats. Among Hispanic voters, young adults and independents, Democrats hold an average advantage of 16 points—a margin that historically points toward a wave election for the opposition party.

Speaker Mike Johnson faces the harder task of holding a fractured caucus together. Infighting and legislative impasses have fed a sense of instability within the majority, compounded by a wave of House retirements that narrows the GOP's runway heading into a competitive cycle.

With only a four-seat cushion, Republicans can afford to lose almost nothing. Even a handful of losses in competitive districts would flip the chamber, putting intense pressure on individual campaigns across swing-district America.

Trump pushed a mid-decade national redistricting effort aimed at reshaping the House map in Republicans' favor. Those efforts have produced a draw, with Democrats and some Republicans contesting the moves, leaving the playing field largely unchanged.

Democrats, despite their own voter-approval challenges, appear positioned to capitalize on Republican struggles. Their overperformance in recent elections shows an ability to mobilize voters when the national environment favors them.

The Republican-held Senate is not insulated from a hostile national environment either. Majority Leader John Thune is working to defend a narrow majority as his party confronts the same headwinds dragging on House Republicans.
