evidence: It’s true, as some of the ads say, that the U.S. average weekly price for a gallon of regular gasoline has more than doubled since Biden has been president. It went from $2.38 the week ending two days before Biden was sworn in on Jan. 20, 2021, to a record of more than $5 the week of June 13, according to the most recent EIA data. [...] But gas prices began rising before Biden’s inauguration. When he took office, the average weekly price had already increased about 60 cents from a low of $1.77 a gallon in April 2020, under then-President Donald Trump. [...] Still, the main factors contributing to high gasoline prices are residual oil supply and demand issues, as well as Russia’s invasion of Ukraine, which continues to cause more uncertainty in the oil market. Prices in the U.S. have not skyrocketed or doubled because of Biden and Democratic policies, as Republican ads lead viewers to believe.
