It could, but I don't know of any method where you always can safely
vote your favorite candidate *above* your compromise choice. If this is
what it would take to avoid two-party domination, then we are out of
luck.

I'm confused. You say that even approval-style voting could move us
towards two-party domination, but that this doesn't worry you because
we have real, stronger, meaningful reasons elsewhere...?

If I were you, I wouldn't be very worried, either. I would feel forced
to give up on this issue.
