Here I read serious thought from r b-j, and will only add a bit.

I like that phrasing.

To decide on a strategy effort is a difficult challenge:
1. What is expectable for vote counts with no strategy - note
that what might be expectable could change if there is more than one
strategy effort, perhaps having different goals.
2. What changes would lead to better vote counts.
3. What might be doable toward such better vote counts, with
minimal risk of causing worse, considering the number of voters needed
to cause success.
Cycles do involve political alignment. In A>B >C>A a triangular
relationship among the three positions is required, as is nearing
equal strength among the three.

Here I choke. Go back to the years in which it was born. What better
could you have proposed then than electing a committee (the EC) to
look intelligently for qualified candidates to elect as Pres and VP?
To have campaigns such as we have now would have been impractical.
Now civilization has advanced and it would make sense to move to
something new.
