Since a POTUS could technically serve for 10 years...

[Sir Mohamed]

I don't think so since the constitution clearly states that no individual shall be elected more than twice. It says nothing about ten years. That's only the result of the rule that a VP who assumes office can run twice if he has served less than two years of the "first" term.

A really interesting question on the 22th amendment is this on the possibility to serve more than ten years: I always use the example for Gerald Ford. If Reagan had chosen him for VP instead of Bush I (what has been considered in real life) in 1980 and Ford had to assume office again, what would have happend? Let's say be becomes prez again in March 1981. Reagan almost died during the assassination attempt. Could President Ford have run again in 1984? If so, Ford would have been prez for more than ten years in total: August 1974 to January 1977 and March 1981 to January 1989.
