President Donald Trump recently claimed on his social media platform, Truth Social, that gas prices were "much higher" during his Democratic predecessor Joe Biden’s administration. However, this assertion drew criticism from both some of his own supporters and analysts. Many users pointed out that gas prices in their states had reached record highs. For example, a user from Michigan noted that gas prices had been as high as $4.49 a gallon during Trump’s presidency and had now climbed to $4.99. Others echoed similar concerns, stating that they had never paid more for gas than they were paying now, and some added that not only were gas prices higher, but food and diesel prices were also worse. The group "Republicans Against Trump" challenged Trump’s claim by comparing average gas prices today with those when Biden left office in January 2025. Their analysis showed that regular gas now averages about $4.48 a gallon, compared to $3.11 under Biden. Diesel prices have also risen significantly, averaging $6.51 today versus $3.72 under Biden. Meanwhile, the Center for Economic and Policy Research found that gas prices averaged $3.35 a gallon during Trump’s second term, slightly lower than the $3.46 average during Biden’s full term. The group warned that if prices continue to rise, Trump might soon be able to claim that gas prices under his administration are higher than under Biden’s. According to analysis by Yahoo Finance, gas prices are currently more than 35 percent higher than they were at the same time in 2024, when Trump promised to bring down costs during his presidential campaign. With seven weeks remaining until the midterm elections, affordability remains a top concern for voters. Trump has attempted to reassure supporters that prices will "tumble down" after the midterms and that the current cost is a "very inexpensive price to pay" for preventing Iran from acquiring a nuclear weapon. Republican strategists have raised concerns about the effect of high gas prices on voter sentiment. Veteran Republican strategist Chris Wilson told the Associated Press that gas prices are a critical economic indicator that voters experience directly and frequently. He emphasized that the high cost is "literally staring them in the face several times a week" and warned against downplaying the frustration of working- and middle-class voters. While some GOP operatives believe that Trump’s supporters understand his actions on Iran, they acknowledged that national security remains a central part of his platform and the broader Republican agenda.
