The rules need to be changed in some way to make this more fun...
What might be good would be the same sort of rules as in "...Kevin Bacon", where the actors in each step have to appear in the same movie together. In this case, they'd have to appear in the same election together (or something else similarly close, such as being closely related...or in the case of foreign leaders, something like appearing at a summit together?). Both being "elected to the Senate"--even at the same time--just doesn't cut it.
Blerpiez' recent one is a pretty good one, I think.
As for Jfern's one:
1)
Robert Morris and
James Madison both attended the Constitutional Convention and signed the Constitution.
2)
Bernie Sanders attended
James Madison High School. (Urgh...but it's pretty impossible otherwise to get from one to the other otherwise).
3)
Bernie Sanders and
Richard Sugarman were roommates. (Thanks Wikipedia!)
4)
Richard Sugarman and
Joe Lieberman were roommates.
5)
Joe Lieberman lost the 2004 Democratic Nomination to
