For the past several months, a White House-led team of economic specialists has marked each day in the same way: With a painstaking, state-by-state examination of gasoline prices and the intricate market forces pushing them relentlessly upward.

Senior officials and others close to President Joe Biden view those prices as the cost that most directly affects voters’ everyday lives, and therefore their perception of the economy as well. As such, Biden and his top advisers fixate on them with an intensity that some aides describe as obsessive. White House chief of staff Ron Klain has grown particularly absorbed by the issue, checking the average price of a gallon of gas every morning. He’s lamented that it’s the one item everyone knows the cost of because gas station billboards are so ubiquitous throughout the country.
