November's midterm elections were always going to be difficult for Republicans, but the war in Iran has made their situation even more dire.
The war has come at a significant cost to American treasure and prestige, weakening its ability to deter other enemies and fraying its alliances.
Despite initial support from some Republicans, wider support for the war failed to materialize, with approval ratings plummeting among Democrats, independents, and even Republicans.
The deal gives Republicans on Capitol Hill little relief, with many expressing concern over the war's effect on prices and the country's ability to respond to future supply shocks.
For Democrats, the war is a political gift, combining an unwanted foreign military adventure with a direct hit to household finances.
