Trump Scores 8-Point Bump and Generic Ballot Tightens During June 2026
The president’s job approval rating significantly improved as he pushed for and signed an overwhelmingly popular peace deal to end the Iran War. Unsurprisingly, the midterm outlook improved for Republicans in June as both Democratic advantages on the Generic Ballot and Trust to Handle Issues deteriorated and fell off historic highs. The survey was conducted by BIG DATA POLL as part of the Public Polling Project for June 2026.
President Donald Trump’s approval rating began to bounce back, improving overall and on every single issue tracked by BIG DATA POLL. That marks he first improvement since the start of the Iran War. Key indicators such as the Direction of Country Index and the White House Policy Focus Tracker also improved by the end of June 2026.
“The war was never popular and voters have been frustrated over what they perceive to be a lack of focus on domestic issues,” BIG DATA POLL Director Rich Baris, said. “But this is the first month since the start of the Iran War the picture was a little rosier for the President and Republicans.”
“That said, these results and the transcripts of interviews conducted make it very clear that the fate of the Republican majorities in November is almost certainly tied to a lasting peace with Iran.”
Iran Peace Deal Overwhelmingly Popular
Worth noting, BIG DATA POLL started interviewing voters about the peace deal to end the Iran War immediately after the president made the announcement. Support initially clocked in just below 70% and opposition failed to reach even 20%. The current result should be read in proper context, which is that its popularity is extremely durable given the assault launched at the president and the deal by those who wish to see an unpopular war continue.
Now, 62.2% of likely voters support the agreement and just 24.1% oppose it, a testament to just how fringe the pro-war has become. Another 13.6% say they are unsure, which has risen amid that assault but still rather consistent.
Generic Ballot for the U.S. House
During the Iran War, Democrats posted two of the largest leads for either party on the Generic Ballot ever measured by BIG DATA POLL. Last month, Democrats expanded their already significant lead over Republicans on the Generic Ballot among likely voters 49.1% to 36.1%.
But in June, their lead among likely voters shrunk to roughly 9 points, 48.0% to 39.1%. Also significant this month, is that Republicans are holding their own with undecided voters and the lean, holding the margin at 50.2% to 41.0% after leaners.
Direction of Country: Right Track OR Wrong Track?
The Direction of Country Index started the year with 36.3% saying the country is headed in the right direction, essentially unchanged from the year-end reading at 36.1%. By the end of May, that percentage fell to just 29.7%, the lowest since former President Joe Biden left office in January 2025. In June, that number has risen again for the first time since the war started, up measurably to 36.7%.
The percentage of registered voters who say it’s off on the wrong track hit 60.4%, the highest since December 2024 and up from last month’s reading at 59.7%. That also marks the widest negative spread since January 2025 at -30.7 compared to just -7.2 in May 2025 before the president bombed three of Iran’s nuclear sites. Now, it has fallen against to 57.1%.
Methodology
The Public Polling Project conducted by BIG DATA POLL interviewed 2,971 registered voters and 2,604 likely voters nationwide from June 26 – 28, 2026. Interviews conducted online are sourced through Lucid (CINT) and live-agent phone interviews including P2P SMS and text-to-online are sourced from either the L2 National Voter File Database. Participants who opted for text-to-online were given 24 hours to complete the interview. Interview details plotted on maps can be reviewed by hovering and clicking on the locator pins. Results were weighted for sex, age, race and ethnicity, education, and geography. The overall sampling error is ±1.8% for the registered voter sample and ±1.7% for the likely voter sample at a 95% confidence level. It is important to note that sampling errors for subgroups are higher. All BIG DATA POLL publicly conducted surveys are crowdfunded via the Public Polling Project, supplemented if necessary by BIG DATA POLL and are NOT funded by or affiliated with any candidate, campaign, committee, or political entity.
