I think we've done this before, but basically the idea here is what else people who served in the White House could have done with their lives had they not become President. Political careers are okay, so long as the White House is not attained. Of course, non political roles are much more interesting. These alternate careers do not have to form a cohesive timeline, this is just brainstorming. To start with here are a few ideas for the President of the postwar era to the modern day.
Barack Obama
Professor of Constitutional Law.
George W. Bush
Baseball Commissioner
Bill Clinton
Jazz Musician
George H. W. Bush
Secretary of State
Ronald Reagan
A B list film actor who found success on television.
Jimmy Carter
Pastor
Gerald Ford
Football Star
Richard Nixon*
Editor in Chief of some conservative newspaper
Lyndon Johnson
Texan Television Tycoon
Jack Kennedy
Editor of the Boston Globe
Dwight Eisenhower:
Serves as President of Colombia University throughout his historical Presidential term
Harry Truman**
Failed businessman.
*This is something of a joke, considering how much Nixon loathed journalists historically, I thought that having him become a journalist would be funny. I understand the plausibility issue
** I can't see Truman having a successful career outside of politics, everything else he did was a failure.
