One big problem is that Mr. Biden often doesn’t seem to know what he’s talking about. Take rising gas prices that are a growing public concern. Mr. Biden blamed the OPEC cartel for not producing more oil, but then he said the answer is “ultimately . . . investing in renewable energy.”

Most cars still run on gasoline, not solar or wind power. Electric cars remain impractical for most Americans. The way to reduce gas prices is to produce more oil to increase the supply. Mr. Biden wouldn’t have to plead with OPEC to produce more if he weren’t working so hard to limit U.S. oil production…

We take no pleasure in pointing this out, since the U.S. needs a President who can handle the strains of the job. Mr. Biden was never Demosthenes, and all Presidents stumble in speech. But Mr. Biden’s frequent public confusion about the major issues of the day is a reason for the growing public concern.
