Midterm Elections One Month Out: Polls and Forecasts Show Democratic Edge Amid Economic Pressures and Historical Patterns

President Trump was elected in 2024 with a focus on reducing prices. Prices have not declined since he took office for a second term. His approval rating stands at 37 percent in an average of recent polls, tied for the lowest pre-midterm rating for any president in the past half century. The only comparable figure in that period belongs to George W. Bush in 2006, when Republicans lost both chambers of Congress.

One month before Election Day, forecasters at the Cook Political Report project a net gain of five to 15 seats for Democrats in the House. That range would produce a Democratic majority between 220 and 230 seats. The Senate map has also moved toward Democrats, with six races shifting in their direction since June. At the start of the cycle, Democratic control of the Senate was considered unlikely; current ratings place it within reach.

These assessments rest on national conditions typical of midterm cycles. History shows the president's party has lost House seats in 18 of the 20 midterms since World War II, averaging 26 seats. Losses average 35 seats when the president's approval rating is below 50 percent. The last three midterm cycles produced smaller losses despite low presidential approval, partly because fewer districts remain competitive.

Multiple structural factors could limit Democratic gains. Mid-decade redistricting has reduced the number of competitive House seats, most of which are now in districts carried by Trump in 2024. Republicans hold a spending advantage in many races. The Democratic Party continues to register low favorability ratings in national surveys. Cook Political Report and similar organizations update ratings frequently in the final weeks; past cycles have recorded shifts of five or more seats in the closing month.

Economic conditions remain the leading voter concern. An AP/NORC poll released last week found 65 percent of respondents attributing higher prices more to Trump's policies than to external factors. Twenty-six percent approved of his handling of the economy. An NBC News poll in September showed Democrats holding a narrow lead over Republicans on which party is trusted more on economic issues, within the margin of error but reversing a prior Republican advantage. The only previous Democratic lead on that question during a Trump presidency occurred in 2018, when Democrats gained 42 House seats.

Administration policies including tariffs and involvement in the conflict with Iran have coincided with higher costs for goods and energy. Inflation has continued to exceed wage growth for many households. Labor market turnover remains low. Wealth gains have concentrated in sectors tied to artificial intelligence, while utility costs have risen in some regions. The Federal Reserve raised interest rates this fall to address inflation, increasing borrowing costs for homes and vehicles. An NPR/PBS News/Marist poll recorded 53 percent of respondents saying they strongly disapprove of the president's job performance, the highest level recorded in that survey.

Republican arguments emphasize that external global conditions and prior policy decisions also shape current prices. The administration has pointed to regulatory reductions and workforce changes as long-term measures to contain costs. Polls show voters assign primary responsibility to the sitting administration regardless of these distinctions.

Turnout patterns add another variable. Midterm participation is typically about 30 percent lower than in presidential years, increasing the weight of voters with strong motivation. A CBS poll released Sunday found 84 percent of Democrats and 82 percent of independents saying they will definitely vote, compared with 77 percent of Republicans. The generic congressional ballot in an average of 2026 surveys shows Democrats ahead by nine points. In each of the past seven midterm elections, the party leading this measure gained seats.

Trump has described the elections as a referendum on his record and urged supporters to treat him as on the ballot. Past Republican campaigns have used similar appeals to increase conservative turnout. Success in competitive districts has also required support from independents and Latino voters, two groups that have shown declining approval of Trump in recent surveys.

The White House maintains that high conservative mobilization can offset broader national trends. Whether that mobilization proves sufficient will be tested in swing districts and key Senate contests, where candidates typically require support beyond core partisan voters.

Forecasts one month before Election Day reflect current polling and structural conditions. They remain subject to change based on events, turnout, and late shifts in voter preference.
