Trump's public support for the Iran war has collapsed to levels rarely seen in modern polling, a serious problem for him and his party heading into the midterms.

• Only about a quarter of voters trust Trump to handle Iran, and support has fallen sharply since he ordered new strikes.
• Even Republican backing has dropped below half, and independents oppose him by nearly eight to one.
• The war brought no clear payoff for the US — dead and wounded troops, over $100 billion spent, and drained missile and oil reserves — while critics say it mainly served Israel's interests.
• On war and terrorism, an issue that normally favors Republicans, the party has swung 20 points toward Democrats.
• Higher gas prices and rising inflation from the conflict are adding to the political pain.

Outlook: With no exit in sight and support still sinking, the Iran war looks set to keep dragging down Trump and Republicans into the midterms.
