As the official referee for this event, I have to declare that neither Nunn or Sebelius count as wild cards. Sebelius is the fourth-most-mentioned VP and lots of people in this forum still predict it will be her. Nunn is the sixth-most mentioned VP after Clinton in the media.
Thanks for hiring me as your referee.
Ah but Mr. Referee you should read how the rules are written...
name a possible (at least a semi realistic pick) who isnt named kaine, bayh, biden or clinton.
Therefore suggestions of Sebelius and Nunn are valid in this contest.
