What happened

The national average price for a gallon of regular gas fell to $4.18 on Saturday, Oct. 31, according to AAA. That is down 2.1 cents from Friday and 11.2 cents from a week ago, the seventh daily drop in a row, according to AAA figures reported by MyNewsLA.

Even with the slide, prices are far above last year. AAA's year-ago national average was $3.04, so drivers are paying about $1.14 more a gallon, or roughly 38% more. Patrick De Haan, head of petroleum analysis at GasBuddy, told CNBC that gas and diesel are on track to be the most expensive ever on an election day, with the midterms on Tuesday. "Prices have never been this high this late in the year," he said.

The price ladder (AAA national average for regular unless noted): about $2.98 on Feb. 28, 2026, when the Iran war began (today's price is $1.20 higher, per AAA figures reported by MyNewsLA); $3.04 a year ago; $3.80 at the November 2022 midterms (AAA, via CNBC); $4.43 a month ago; $4.30 a week ago; $4.20 on Friday; and $4.18 on Saturday. The all-time high is still $5.02, set June 14, 2022.

Why it matters

Gas is one of the prices voters see every day, and it has become a campaign issue. In September 2024, Donald Trump pledged at the Economic Club of New York to bring gasoline "below $2 a gallon," CNBC reported. De Haan said GasBuddy had predicted last December that 2026 would be the cheapest year for gas since 2020, before the war with Iran pushed oil higher. "Trump got in his own way," he told CNBC.

More context

Diesel, which moves the trucks that carry food and goods, is worse. AAA's diesel average is $6.31 a gallon, just below the record of $6.53 set on Sept. 22, 2026. CNBC put diesel up about 70% from a year ago.

How outlets framed it: CNBC led with the election-day record and Trump's $2 pledge. Fox Business focused on the contrast between big oil-company profits and pain at the pump, and noted that September's consumer price index showed gasoline up 34.2% from a year earlier. On Fox Business, former White House economic adviser Larry Kudlow argued that media coverage puts too much weight on gas prices.

The White House's case: Spokeswoman Taylor Rogers told CNBC, "Once this conflict comes to an end, gas prices will drop drastically, and the Iranian terrorist regime will not have a nuclear weapon." The White House also said that, adjusted for inflation, prices were higher around some past election days; it did not give figures in the CNBC report, and US Brief has not checked that comparison. CNBC listed steps the administration has taken, including an executive order on off-road diesel for truckers, $8 billion in relief for farmers and a deal with Russia for about 6 million barrels of diesel.

What the evidence shows: Prices swing widely by place. GasBuddy's weekly report on Oct. 26 put the national median at $4.09, with the most common price at $3.99; the cheapest 10% of stations averaged $3.44 and the most expensive 10% averaged $5.66. In Southern California, the Los Angeles County average fell to $5.98, its 29th drop in 30 days, after California allowed an early switch to cheaper winter-blend gas on Sept. 28, MyNewsLA reported.

What's still unknown: Whether the drop lasts. Brent crude, the global oil benchmark, rose more than 13% in October and U.S. crude rose 15%, CNBC reported. "Worldwide oil prices have increased in the last two weeks due to continued supply volatility, so it is uncertain how long pump prices will continue to decline if that trend holds," Kandace Redd of the Automobile Club of Southern California told MyNewsLA. Trump has said he will not resume strikes on Iran before the midterms; De Haan said a later escalation "could obviously put upward pressure on prices just ahead of Thanksgiving."

Editorial sourcing notes

Prices are AAA's national averages as posted Saturday, Oct. 31, 2026; CNBC and Fox Business cited AAA's Friday figure of $4.20. The Feb. 28 price is calculated from MyNewsLA's report that today's average is $1.201 above the start of the Iran war. The election-day record is GasBuddy's forecast, not a final number. The White House's inflation-adjusted comparison is reported as its claim; the sources reviewed did not include its figures.
