US politics and the Iran conflict are colliding, and it looks bad for Trump and Republicans heading into the midterms.

• Trump paused planned strikes on Iran because the US is running low on air defense munitions, fearing Iran could hit back.
• The war could cost $80–100 billion or more, dragging on the economy and worrying Republican voters.
• Some three-time Trump voters now regret it, pointing to higher gas prices, no promised rebate checks, and a new war.
• Polls show tight midterms — the House leans Democratic, the Senate is a toss-up, and one in five Republicans may stay home.
• The fight is also about money in politics, with attention on Citizens United, billionaire super PACs, and Elon Musk's growing wealth versus a flat minimum wage.

Outlook: Republican control of Congress looks shaky if voter frustration over the war and gas prices holds through the midterms.
