Rising gas prices since the beginning of the Iran War are a key issue during the 2026 midterms.
Since last year, regular gas prices have increased by 40%, and diesel prices by 71% across states.
Michigan, a key battleground state, saw the second-sharpest rise in gas prices after Wisconsin.
For many voters, their choice in the midterm elections could come down to one thing: the pain at the pump .
Since the Iran War began in February, higher fuel costs have become a growing pressure point for Americans. Disruptions in the Strait of Hormuz , a critical global shipping chokepoint, have tightened global fuel supplies and pushed energy prices worldwide.
On average, regular gas prices in the US today are nearly 40% higher than a year ago, according to AAA’s Fuel Price Tracker as of November 2. In 42 states, regular gas prices per gallon today are at least $1 higher than they were a year ago.
For diesel fuel , which is used in industries like agriculture and manufacturing , as well as for transporting goods, the rise has been even sharper. Across all US states , diesel prices have risen by 71% on average.
Almost every US state recorded its highest-ever diesel prices this fall, with the exception of Rhode Island, Massachusetts, and New York, which saw higher prices in 2022, when Russia’s invasion of Ukraine sent global fuel prices soaring.
A White House spokesperson told Business Insider that once the conflict in the Middle East ends, gas prices will “drop drastically,” adding Iran also “will not have a nuclear weapon.”
“Thanks to the exceptional work of the US military, more oil is now flowing out of the Persian Gulf than before the Iran conflict began,” the spokesperson said.
To see how fuel prices have risen across the US, Business Insider used AAA data to compare today’s gas prices with those a year ago. We ranked all US states by the percentage increase in regular prices, which most people see at the pump . We also listed the rise in diesel prices in each state to provide a fuller picture.
