Democrats Pull Ahead in Midterm Polls as Trump’s Approval Dips Amid Iran War Fallout
By Drooid · · How we work
Core Event
A new national survey by Marquette Law School shows 54 % of likely voters would choose Democratic candidates for Congress, while 41 % would back Republicans. The poll, conducted in early September 2026, also records a decline in President Donald Trump’s approval, with only 37 % rating his performance positively. A Reuters/Ipsos poll released on September 14 2026 reports a narrower Democratic lead—44 % to 37 %—and a Trump approval of 35 %.
Background & Context
President Trump’s second term has been dominated by a war launched against Iran in February 2026. The conflict has disrupted Middle-Eastern oil shipments, contributed to near-record fuel prices, and heightened concerns over inflation and the cost of living. Voters cite the economy, inflation, and health-care as areas where Democrats are perceived as stronger, while Republicans are viewed more favorably on national defense, crime, and immigration/border security.
Data & Statistics
| Metric | Marquette poll (early Sept 2026) | Reuters/Ipsos poll (Sept 14 2026) |
|---|---|---|
| Likely-voter support for Democrats | 54 % | 44 % |
| Likely-voter support for Republicans | 41 % | 37 % |
| Trump approval (overall) | 37 % approve, 63 % disapprove | 35 % approve, 65 % disapprove |
| Sample size (Marquette) | 1,023 adults (581 likely voters) | 1,143 adults |
| Margin of error (Marquette) | ±4.3 % for likely voters | ±3 % |
The Marquette poll also finds voters view Democrats as better on the economy, inflation, Medicare/Social Security, and health-care, while Republicans are seen as stronger on defense, crime, and immigration/border security. Majorities opposed data-center construction, AI impacts, and “Flock” surveillance cameras.
Official Statements & Responses
President Trump has asserted that the United States, not Iran, controls the Strait of Hormuz and predicted oil prices will fall “right after the election.” Republican leaders at the recent midterm convention in Dallas urged candidates to align closely with his agenda despite his low approval ratings.
Conflicting Reports & Gaps
- Poll margins: Marquette shows a 13-point Democratic advantage among likely voters; Reuters/Ipsos indicates a 7-point gap. Different methodologies and sample sizes produce divergent estimates.
- Trump approval figures: Reuters reports 35 % approval, Fox 11 cites 37 %, and other outlets note 38 % among likely voters, reflecting variations in respondent pools and timing.
- Impact of the Iran war: Sources link the war to higher fuel prices and inflation, but precise causal attribution to voter behavior remains unquantified.
Why It Matters
The expanding Democratic lead in generic-ballot polls suggests a challenging environment for Republicans seeking to retain control of the House and Senate. Persistent low approval of Trump—particularly on economic issues tied to the Iran conflict—could influence down-ballot races, as voters associate foreign-policy choices with domestic cost-of-living pressures. The convention’s emphasis on unwavering support for the president indicates internal party tension over electoral strategy.
What’s Next
Congressional elections will be held in November 2026. Polls will continue through the campaign season, and both parties are expected to adjust messaging in response to evolving public opinion on the economy, inflation, and the ongoing Iran war.
