Assuming we really want this clause, we should try to get it
complete: what happens in the case that 3b+3c eliminates all
options?  I guess the default option should win then?

And do we really want to drop the default option at this point?  If
this is the case, we could add a sentenct like "note that this removes
the default option from the ballot".

I asked this before: is the concept of "dropping a defeat"
really clear without explanation?  At least it is not clear to me.
Does it mean dropping the defeated option?  Or setting the values
in two cells of the tally table to 0?

How could there be defeats within the Schwartz set at this point?
Couldn't we simply write "The elector with the casting vote chooses
the winner among the remaining options"?

I hope this helps,
