He’s 77 years old. When Trump was born, Harry S. Truman was president and Perry Como topped the year’s pop charts. Betty White hadn’t yet started her career in film. Israel and Pakistan didn’t exist. Korea was a unified country, and Vietnam was not. The pioneering computer ENIAC was just four months old.

Trump’s cultural references are dated, and only getting more so. Elton John and the Rolling Stones headline his rally playlists. When, as president, he had a chance to award the Presidential Medal of Freedom, the nation’s highest civilian honor, his selections included Babe Ruth (who died in 1948) and Elvis (who died in 1977—perhaps).

The same goes for his political touchstones.

[Allow me a “Yes, but …” Trump clearly has enormous energy, and so far hasn’t shown any signs of age-based deterioration. Joe Biden, on the other hand, can barely walk on stage without handlers, can’t speak extemporaneously without notecards, and always sounds on the edge of exhaustion when he isn’t yelling in a strangely agitated manner. The reason that no one’s ‘noticing’ Trump’s age is Biden’s clear deterioration. Still, it *should* be a topic of discussion, because at 77, there’s no guarantee against decline over the next five years. — Ed]
