What happens if one of the Presidential candidates dies, in between now and election day? I can think of three logical replacements.
1. Their vice-president candidate (Kaine or Pence)
2. The runner-up candidate from the primaries (Cruz or Sanders)
3. The highest-ranking member of their party (Ryan or Biden)
I know the VP takes over if the President dies after election day, but what about before election day? What if the candidate dies, after the primaries but before announcing a VP?
