Do you think politicians are too old and sleepy? Currently, President Biden is the oldest US President ever, at 81 years old. The oldest senator, Chuck Grassly, is 90 years old. The median age of a US Senator is 65. That’s the age of retirement! Representative Nancy Pelosi, 83, former House speaker, announced she would run for re-election in 2024, surprising everyone by seeking a 20th term that she would finish at age 86. Should we have a cut off age for politicians?
