In reply to: I believe most religious orders require retirement by 70... posted by Kbyrnes
You turn 80 seems about right. Parties would likely avoid people older than 71 for a 1st term. Maybe a party would nominate a Biden in 2016 with the expectation of a primary in 4 years.
It's pushing it for most but I think there are a good number of 70 somethings who could do the job.
