Hi all,
We're all aware that Ronald Reagan is to date the oldest person to serve as US president, taking office just before his 70th birthday.
Your challenge, should you choose to except it, is to enable him to become the youngest president, with as late a Pod as possible.
He can either be elected in his own write or become president through succession, though you get bonus points if he's elected in 1948 (which I think is the earliest possible oppertunity, given presidencial rules).
He can either be elected as a Democrat or Republican, ideologically to the left or right, just as long as it's plausible.
