When Democrats have spoken recently, it’s often sounded as if they’re living in a different reality than most Americans.

A good example is President Biden’s response Tuesday when asked if he was worried about the August inflation report: “No, I’m not, because we’re talking about one-tenth of 1%.” Actually, we’re talking about an 8.3% year-over-year increase in the consumer-price index. Mr. Biden focused on the monthly inflation rate and ignored that economists had expected prices to decline in August.
