Put some ice on it, Bill.
I will say this, and not in defense of Clinton, particularly.
Times have changed. Airline schedules make things possible that were not possible in the past. Clinton and Carter gallop about and seem to want their faces on TV all the time and are irritating in the context that "other former presidents don't do this".
Well, other former presidents of the past didn't have the travel infrastructure that exists today. Bush Sr. is a great deal older than Clinton and even he made tsunami trips and got TV face time. Carter has been doing this stuff since he left office, but again because he was young enough and because airlines made it possible.
Point being, the role of ex presidents will not always be what the past defined.
