Michael Dimock, associate director at the Pew Research Center, suspects that voters won't exactly thank Obama for $3.75 a gallon gasoline. Still, it dulls a weapon that his presumptive Republican challenger, Mitt Romney, would like to use to unseat the president.
And Obama can look forward to further help this fall. After Labor Day, refiners can begin using cheaper ingredients to make gasoline because wintertime clean air rules are less stringent. That should push gasoline prices lower between Labor Day and Election Day, barring hurricanes that can disrupt supplies or other global events, says Kloza.
"History will be working on behalf of the Democrats," he said.
