I am trying my best to find when, in recent history these three events have taken place in an election campaign:
1) The credentials of the Vice Presidential candidate have been expected to stand up to the credentials of the Presidential candidate on the opposing ticket.
2) The Vice Presidential candidate is expected to have any Foreign Policy experience whatsoever.
3) The Vice Presidential candidate has had his/her family attacked in order to make them a campaign issue.
I can only come up with one example. The Election of 2008.
