Polls show the Iran war is one of the most unpopular in US history, which is bad news for Trump and Republicans heading into the midterms.

• The war's approval sits 40 points underwater, with 68% of Americans saying it wasn't worth it — worse than the Iraq war.
• Even Trump's own base is souring: most MAGA voters blame the war for rising gas prices, with oil close to $100 a barrel.
• Republicans have lost their edge on their strongest issues — Democrats now lead on the economy, inflation, and even immigration.
• Senate races once seen as safe, like Maine and Iowa, are slipping as gas prices and war fatigue hit rural voters.

Outlook: Gas prices and war anger point to a large Democratic wave in the midterms, and ending the war now likely won't reverse the damage.
