Simply, the process happens without interference from the Omnipotent Force. The usual nomination process for all parties, and a “normal” election.
For the late entrants here, a hypothetical choice:
1) Jeb Bush wins the 2016 election for sure, guaranteed by a Higher Power, or
2) A “normal” election with no Higher Power interference
Which would you choose?
Whose Higher Power? The Lord Almighty? Or Obama’s Moon God?
