Hi Mike,
I don't think Approval-Runoff can get off the ground since it's too
apparent that a party could nominate two candidates (signaling that one
is just a pawn to aid the other) and try to win by grabbing both of the
finalist positions. If this happened regularly it would be just an
expensive version of FPP.
Actually, it would be an expensive version of Approval.
Still, I am not sure why it would be any easier to propose an approval
runoff vs. plain approval.
It could be better than Approval in one particular case. In a
Gore/Nader/Bush situation where Nader's support is so close to Gore's
that the Nader-voters don't know whether to approve one or two
candidates, a runoff would let them approve of both with little fear,
since the worst that can happen by overestimating is that both Nader and
Gore go to the runoff, in which case Nader would win if he really had
greater support.
However, that advantage is lost if the parties start cloning the
candidates. To keep it, I think one would have to have an exhaustive
runoff, and that would be very impractical.
