President Donald Trump is facing new political pressure as gas prices surge nationwide due to the ongoing conflict with Iran. The national average gas price has climbed to $3.53 per gallon, up 59 cents over the past week, creating a new midterm headache for Republicans as they head into the upcoming elections. The steepest price increases have been in key battleground states, potentially sharpening attacks from Democrats over energy costs and inflation.

Why it matters

Rising gas prices are squeezing Americans already worn down by inflation, creating a new political flashpoint ahead of the midterm elections. Control of Congress is at stake, and uneven gas price spikes could become a key issue, especially in hard-hit battleground states where the regional divide in prices could sharpen partisan attacks over energy costs.

The details

With the Iran conflict rattling oil markets and raising fears of supply disruptions, gas and diesel prices are climbing rapidly nationwide. Oil prices have surged past $100 a barrel for the first time since 2022, driving up the national average gas price by 59 cents to $3.53 per gallon. Diesel prices have also jumped, with the national average up 97 cents to $4.72 per gallon. The steepest week-over-week increases were in key battleground states like Indiana, Florida, Michigan, Ohio, and California.

What they’re saying

“I will not allow a terrorist regime to hold the world hostage and attempt to stop the globe's oil supply. And if Iran does anything to do that, they'll get hit at a much, much harder level.”

What’s next

The White House is weighing steps to protect shipping lanes in the Strait of Hormuz and keep prices from climbing further, as that waterway is critical to global energy supply.

The takeaway

Rising gas prices driven by the Iran conflict are creating a new political pressure point for Republicans heading into the midterm elections, as Democrats look to capitalize on the pocketbook pain felt by Americans already struggling with high inflation.
