Richard Miniter writes, “By the way, both Fox and MSNBC are wrong when they report he was elected to the Senate at age 29. He ran for the office at that age, but was 30 when he was sworn in.” No, they are not wrong if that is how they phrased their reports because being elected and being sworn in are two separate things. Joe Biden was elected to the Senate on November 7, 1972. He was born on November 20, 1942. That means he was 29 when he was elected but turned 30 thirteen days later, making him old enough under the Constitution to take office in January 1973.
