Veepstakes speculation is rampant as we approach the national conventions for both major political parties.

Media reports have detailed the wide array of options available to Donald Trump and Hillary Clinton as they decide who will be their number twos for this campaign, and perhaps for four or eight years to come.

Who will Trump and Clinton pick? That depends on each candidate’s goals – both for the remainder of the presidential campaign and after Nov. 8. Political observers widely agree that the most important characteristic to look for in a running mate is the ability to serve as president in the event of unforeseen circumstances, like a president’s death, incapacitation, resignation or impeachment.
