With only four weeks left until the November 2026 midterm elections, multiple polls and forecasting models indicate that the Democrats have become the clear frontrunners for control of the House of Representatives, with a roughly 50% or even slightly higher probability of gaining a net gain of four seats and securing a 51-49 majority in the Senate. President Trump's national job approval rating has plummeted to a historic low of 32%-38% (some polls show a net approval rating of -23%), and has also declined significantly in several red states such as Texas, Ohio, and Iowa. This contrasts sharply with his nearly 50% popular vote share in 2024, with particularly noticeable losses among independent voters, Hispanics, and young voters. Combining forecasts from institutions like Nate Silver, state-level polls from YouGov, and agricultural bankruptcy data, Trump's low popularity and primary interference are amplifying the Republican Party's structural disadvantages, while inflation, the costs associated with the Iran war, and the impact of tariffs are further tilting the tide of the election. Trump's Low Approval Ratings and Policy Drag Trump's political capital from his election has clearly evaporated. His national approval rating remains low, with some polls even reaching a career low (around 32%), and the data in Republican states is equally poor. The issue of inflation, which is of utmost concern to voters, has not been adequately addressed, and his personal projects (such as the White House banquet hall) have reinforced the impression of "neglecting people's livelihoods." Meanwhile, over half of potential voters believe he has used his position to benefit relatives and friends. Soybean exports are expected to plummet in 2025, and the conflict with Iran is driving up the cost of agricultural inputs such as diesel and fertilizer. Farm inputs are already far exceeding income, and the number of bankruptcies is expected to increase by approximately 46% year-on-year in 2025, continuing to climb in 2026. These factors make the Senate race in Midwestern agricultural states exceptionally fierce, with unexpected changes occurring in traditionally Republican states such as Iowa, Kansas, and Nebraska. Other media analyses also point out that the Iran war and trade policies are eroding the Republican Party's traditional advantage in rural areas. Primary Election Interference Amplifies Republican Risks Trump's aggressive intervention in the Republican Senate primaries has become a "collection of counterexamples." He strongly endorsed Ken Paxton, a candidate favored by MAGA, to challenge Texas incumbent John Cornyn, turning what was once a secure seat into a highly competitive battleground. Democrat James Talarico currently leads or is tied in most polls. In South Carolina, he supported the sister of the late Senator Lindsey Graham, raising questions about her qualifications, and her lead is far smaller than Trump's 18-point advantage in the state in 2024. In North Carolina, he threatened to challenge Thom Tillis in the primary, forcing him to retire and nearly handing the seat to Democratic Governor Roy Cooper. His long-standing feud with Governor Brian Kemp in Georgia indirectly solidified the position of incumbent Democratic Jon Osoff. Multiple forecasting agencies have identified Texas, Ohio, and Iowa as key swing seats, significantly increasing the probability of a Democratic upset. Structural Opportunities and Hidden Dangers for the Democratic Party Favorable factors include: higher Democratic voter enthusiasm and greater likelihood of voting; a shift in Hispanic support weakening the effects of redistricting; the Supreme Court's elimination of some Black-majority House districts potentially stimulating Black voter turnout; public concerns about artificial intelligence putting the Republican Party at odds with public opinion; and a greater number of voters viewing the Republicans as "too extreme" (56% vs. 44% for Democrats). In the House, the Democrats are expected to gain double-digit net seats, with a generally 70%-90% chance of control. However, the Democrats also have weaknesses: unexpected competition in New Hampshire, Minnesota (due to the governor's handling of a Somali community social services scandal), and Michigan (where progressive candidates received relatively low vote shares); if these states are lost, they will need to win multiple seats in states where Trump is expected to lead significantly in 2024, greatly increasing the difficulty. Whether financial disadvantages and a counterattack on "communism" issues will be effective remains to be seen. Missed Historical Opportunity and Outlook for 2028 Regardless of the final outcome, Trump has missed the opportunity to translate a 2024 victory into a lasting Republican reorganization. Independent voters, Hispanics, and young people who once flocked to him are now the main critics. With both major parties experiencing declining support, and 2028 bringing an election without a sitting president, candidate selection, policy setting, and party positioning will be even more decisive. The current election is more like a referendum on governance than a simple battle of party loyalty. Other analyses also emphasize that low presidential approval ratings have historically been highly correlated with midterm defeats for the ruling party, and the risk of a "red tide reversal" facing the Republican Party is particularly pronounced this time.
