Trump Freefall Spurs Midterm Bloodbath?

President Trump’s approval rating has sunk into the low-to-mid 30s, and history shows presidents this unpopular tend to lose far more seats in Congress than those who stay above 50%.

Story Snapshot

An aggregate of polls put Trump’s approval at 34.9% and disapproval at 62.1% as of late September 2026.
A Reuters/Ipsos poll found Trump at 32% approval, his lowest mark in that poll across both terms.
Gallup data since 1946 shows presidents below 50% approval saw their party lose an average of 37 House seats, versus 14 seats for those above 50%.
Analyst G. Elliott Morris estimates every 10-point drop in approval costs the president’s party roughly 20 more House seats.
The president’s party has lost House seats in 39 of the last 42 midterms, a pattern political scientists call the “presidential penalty.”

Approval Numbers Keep Sliding

Multiple polls now show President Trump struggling with voters ahead of the 2026 midterms. A FiftyPlusOne aggregate placed his approval at 34.9% as of late September, with disapproval at 62.1%. A Reuters/Ipsos survey found him even lower, at 32%, which the poll’s backers called his weakest reading in either of his two terms. Pew Research reported Trump trailing where Barack Obama, Bill Clinton, and Ronald Reagan stood before their own midterms.

Pollsters stress these numbers aren’t identical. Reuters/Ipsos measures U.S. adults, while an NBC News poll of registered voters showed Trump at 41%, a notably higher figure. Different samples, field dates, and question wording mean the numbers shouldn’t be treated as interchangeable. Still, nearly every major pollster agrees on the broader direction: Trump’s support has fallen sharply since he took office at roughly 52% approval earlier in his second term.

What History Says About Low Approval

Gallup has tracked presidential approval against midterm seat losses back to 1946, and the pattern is consistent. Presidents polling below 50% approval saw their party lose an average of 37 House seats. Those above 50% lost just 14 seats on average, a gap that reflects a correlation of 0.66 between approval and seat losses. George W. Bush sat at 38% approval before 2006, when Republicans lost 30 seats. Barack Obama stood at 45% before 2010, when Democrats lost 63 seats.

Analyst G. Elliott Morris, who has studied this relationship closely, estimates that every 10-point drop in approval corresponds to roughly 20 additional House seats lost by the president’s party. Applied loosely to Trump’s current numbers, that formula would suggest a rough midterm for Republicans. But Morris and other researchers caution the relationship is a trend line, not a guarantee, since individual elections vary widely based on local conditions.

Correlation Is Not a Crystal Ball

The 0.66 correlation Gallup reports means approval explains a meaningful share of seat losses, but it leaves plenty unexplained. Economic conditions, candidate quality, local turnout, redistricting, scandals, and foreign conflicts can all shift outcomes independently of how voters rate the president. Obama’s 2014 midterm, for example, brought a relatively modest 13-seat loss despite approval numbers similar to his disastrous 2010 showing, proving the pattern isn’t automatic.

Researchers have long described this dynamic as a “presidential penalty.” Studies show the party holding the White House has lost House seats in 39 of the last 42 midterm elections, regardless of who’s in office or how popular they are. Political scientists trace this partly to voters using midterms as a check on the party in power rather than a direct referendum on the president himself.

That history matters for both parties right now. Republicans control the House and Senate, and a historically rough midterm would hand Democrats real power to block President Trump’s agenda for his final two years. But voters frustrated with Washington on both sides of the aisle may see this less as a partisan story and more as proof that no single party stays trusted for long once it holds power. The numbers don’t guarantee an outcome, but they do show why both parties are watching this approval slide closely as Election Day approaches.
