As the 2022 midterm elections approach, FedEx CEO Fred Smith said Wednesday that former President Barack Obama once remarked that his poll numbers "were almost perfectly correlated with the price of gasoline" on "Special Report."

Smith added that gas prices are "a big issue, and previous decades show that when fuel prices run up, they act as a retardant or a tax on consumption. So we'll see this summer whether people are still buying goods to the same degree that they have been in the past. And of course, if they don't, a lot of the port problems … will go away because there'll be [fewer] goods moving through the ports."

Whether high gas prices will act as a tax also depends on OPEC and Saudi Arabia's course of action. With Russian fuel "largely embargoed" worldwide, "that could create its own set of problems."

A unique set of problems will also arise from China's lockdowns and lack of production, with its ports and factories being "a big thing."

The country has approximately 27% of the world's manufacturers within its borders.
